higher to support the Probe Module 2. The current firmware version can be checked

from the Apex Display on the Self Test screen. If needed, please upgrade the Apex Base

Module firmware to 4.02 or higher before proceeding with the installation. See the Apex

Setup and Programming Guide for firmware upgrade instructions.

The AquaController Probe Module 2 should be securely mounted in a location free from

moisture. Use wood screws through the mounting tabs of the probe module case or if

mounting on drywall, use drywall anchors (mounting hardware not included).

Apex Probe Module 2 (PM2) - Setup Guide Page 4

•Mount all modules above the water line of the aquarium.

•Be sure to utilize drip loops on all power cords, AquaBus cables and probe cables.

WARNING: Water damage will void your warranty! Mount all modules in locations

safe from moisture exposure.

INITIAL CONNECTIONS

Plug one end of the included AquaBus cable into one of the AquaBus ports on the probe

module and the other end into an available AquaBus port on your existing Apex system.

It makes no difference which AquaBus port is used and you do not need to power down

the system when connecting AquaBus accessories as the system is plug-and-play.

WARNING: NEVER plug standard USB devices into any AquaBus connector or

AquaBus accessories into computer USB ports. Damage to the AquaBus accessory

and/or USB device may result.

Connect the Conductivity probe (must be purchased separately, available from your

Neptune retailer) to the port labeled Conductivity on the Probe Module 2. Push the Mini-

DIN 4 connector into position paying close attention to the pin alignment.

If you are using a temperature probe with the Probe Module 2 (must be purchased

separately, available from your Neptune retailer), plug in to the port labeled Temp on

the probe module and place the other end of the Temperature Probe in the aquarium

water in an area of medium to high flow in the same area as the conductivity probe.

STARTUP

As soon as the probe module is connected to an active AquaBus, the probe module will

power up and begin to initialize. When first connected to an AquaController Base Module

(through the AquaBus), the probe module will automatically be assigned an AquaBus

address and be added to the AquaController configuration. The LED Status indicator on

the probe module will flash yellow while it is being initialized. Once initialized, the LED

Status indicator will be solid green. The LED Status indicator will flash yellow when the

probe module is powered on and communication with the AquaController Base Module is

lost.

VERIFY THE INSTALLATION

Verify the probe module was initialized and added to the AquaController Apex

configuration:

Apex Display: Setup – Module Setup – Modify Name – from this screen, you can

see all AquaBus modules installed on the system.

Apex Probe Module 2 (PM2) - Setup Guide Page 5

Web Interface: Configuration – Module Setup – Verify the probe module is listed

in the Apex Module List.

UPDATE PROBE MODULE FIRMWARE

A new version of firmware for probe modules may be included with Apex Base Module

firmware updates. You should check the firmware version status when the probe module

is first installed and after updating the AquaController Base Module firmware. See the

section titled Updating Firmware in the AquaController Apex Setup and Programming

Guide for instructions to update AquaController Apex Base Module and probe module

firmware.

To check or update an Apex module firmware:

Apex Display: Setup – Module Setup – Update Module – use the up/down arrows

to highlight the Apex module to update, push Select to update.

Web Interface: Configuration – Module Setup – in the Module Configure area, in

the Module: box, select the Apex module to update from the dropdown list, click

the Update Firmware radio button, click the Submit Module Update button, a new

browser window will open to display the update status.

CONDUCTIVITY PROBE SETUP

To enable the Conductivity probe:

Apex Display: Setup – Cond Setup – Cond Enable – If you have more than one

Conductivity port on your system, use the up/down arrow keys to choose the port

you wish to configure, press Select, then use the up/down arrow keys to select

on/off for that port, press OK when done or Exit to discard changes.

CONDUCTIVITY RANGE

The PM2 supports 4 conductivity ranges to support the conductivity measurement of

various solutions. The four ranges are described in Table 1 - Conductivity Range Options.

NOTE: When the conductivity range is in salinity mode, the probe is still actually reading

the conductivity of the water. Since the ratio of ions in salt water is very well defined,

there is a direct correlation between the conductivity of the water and the salinity of the

tank.

NOTE: If the conductivity range is changed, don’t forget to update outlet programs that

are based on the conductivity reading as the values will change with the change in

range.

Table 1 - Conductivity Range Options

To select the Conductivity range:

Apex Display: Setup –> Cond Setup –> Cond Range – If you have more than

one Conductivity port on your system, use the up/down arrow keys to choose the

port you wish to configure, press Select, then use the up/down arrow keys to

select the range for that port, press OK when done or Exit to discard changes.

TEMPERATURE COMPENSATION

Conductivity measurements are temperature dependent. The degree to which

temperature affects conductivity varies from solution to solution. Seawater typically has

a temperature correction factor of 2.1 to 2.3%/C. In order for the PM2 to automatically

compensate for changes in conductivity as the temperature of the water changes, you

must connect a temperature probe to the PM2 and set the temperature compensation as

described below. The temperature probe connected to the Apex Base Module cannot be

used for automatic temperature compensation on the PM2.

WARNING: Temperature compensation value MUST be set to 0.0 if no temperature

probe is attached to the PM2

To set the Temperature Compensation:

Apex Display: Setup – Cond Setup – Temp Comp – use the up/down arrow keys

to select the temperature compensation in %/C, press OK when done or Exit to

discard changes.

NOTE: Leave the Temperature Compensation set to 0.0 if you are not using temperature

compensation or do not have a temperature probe attached to the PM2. Other

temperature probes on the system cannot be used for temperature compensation of the

conductivity probe.

Apex Probe Module 2 (PM2) - Setup Guide Page 7

CONDUCTIVITY PROBE CALIBRATION

NOTE: Set the Conductivity Range and Temperature Compensation settings before

calibrating the Conductivity Probe. See the previous section for instructions on setting

these parameters.

To calibrate a Conductivity probe:

Apex Display: Go to Setup –> Cond Setup –> Cond Calibrate

1. If you have more than one Conductivity probe enabled on your system, use

the up/down arrow keys to choose the probe you wish to calibrate, press

Select.

2. Remove the conductivity probe from the tank and rinse with RO/DI water,

then dry it off. It is not necessary to let the probe dry out – just gently

shake off excess water and blot the tip with the corner of a paper towel.

3. Wait for the numbers on the bottom of the LCD screen to stop changing. It

does not matter what value is displayed only that it is not changing. When

the display stops changing press the select button.

4. Use the Up and Down buttons to select the calibration solution. Press the

select button when the correct value is displayed. See Table 1 -

Conductivity Range Options for the recommend calibration solution.

5. Place the Conductivity probe into the calibration solution. Wait for the

numbers on the bottom of the LCD screen to stop changing. When the

display stops changing press the select button.

6. The conductivity probe should now be properly calibrated.

NOTE: Many conductivity calibration solutions do not have the same ionic

composition as salt water so using a refractometer to measure the salinity of the

calibration solution is not valid. For example the Neptune 53.0 mS/cm

conductivity calibration standard will not have a salinity of 35 PPT or a specific

gravity of 1.0259.

CONDUCTIVITY PROBE MAINTENANCE

Conductivity probes should be periodically cleaned for best performance. The period

between cleanings is up to the user but typically every 1-3 months is normal. To clean

the probe, gently brush the sides and tip of the probe with a soft brush to remove any

debris. Rinse the probe in tap water. Soaking the probe in acid (vinegar) or alkali (borax)

solution to remove mineral deposits is not typically needed but can be used to try and

bring back an old probe that has stopped working.

Apex Probe Module 2 (PM2) - Setup Guide Page 8

SWITCH INPUTS

The PM2 has a Mini DIN8 connector for switch inputs labeled I/O. These inputs can be

used for switches, float switches, flow sensors, etc. Switch inputs connected to probe

modules will be identified as Swx3_2, Swx5_3, etc. The first number in the switch name

corresponds to the AquaBus address assigned to the probe module. The second number

corresponds to the switch input number (1 - 6).

WARNING: Do not apply voltage to the switch inputs or damage to the

AquaController Apex may occur.

The pin-out of the connector is shown in Figure 1 - Switch Input Connector. Connect

switches to the AquaController Apex by connecting one wire from the mechanical switch

to the ground pin (pin 8), and the other wire from the switch to one of the six digital

inputs (pin 1-6). Connections can be easily made using a Neptune I/O Breakout box

available at your local Neptune Retailer. The breakout box features spring loaded

connectors to make connections easy without tools or soldering.

The Apex and accessory inputs are TTL level (5V) inputs with internal pull-up resistors.

With nothing connected, the switch inputs will indicate OPEN (Logic 1 - 5V). When

connected to Ground (Pin 8) the switch will indicate CLOSED (Logic 0 - 0V).

Table 2 – Switch Input Connector Pin-out

Apex Probe Module 2 (PM2) - Setup Guide Page 9

Switch Inputs are programmed using the If switchname command. For example, if you

wanted to turn a pump on when a float switch closes, you would add this command to

the pump outlet program:

If Swx5_1 CLOSED Then ON

The example above assumes that you have a breakout box connected to a PM2 which

has AquaBus address 5, and that the float switch is connected to Input 1 on the breakout

box.

See the section titled Appendix 3 – Programming Reference and Appendix 4 – Advanced

Programming Examples in the Apex Setup and Programming Guide for more information.

PROGRAMMING

The Conductivity probe will be identified as “Condx3”, “Condx4”, etc in the Apex system.

The number in the probe identifier corresponds to the AquaBus number assigned to the

PM2.

If a temperature probe is connected to the PM2, it is identified as “Tmpx3”, “Tmpx4”,

etc. with the same AquaBus number as the conductivity probe.

Switch inputs connected to probe modules will be identified as Swx3_2, Swx5_3, etc.

The first number in the switch name corresponds to the AquaBus address assigned to the

probe module. The second number corresponds to the switch input number (1 - 6).

NOTE: The Conductivity reading can be added to the Apex Display and Web Interface

Status Screens. See the section titled Display Setup in the Apex Setup and Programming

Guide for more information.

The following are some valid program statements (assumes that probe module is

installed and configured on AquaBus address 4).

If Tmpx4 > 80.0 Then ON

If Condx4 > 53.0 Then ON

If Swx4_2 CLOSED Then OFF

Please see the Programming Outlets section of the Apex Setup and Programming Guide

for more information on programming the AquaController Apex.
