Introduction

This document contains information on the operation, installation and

maintenance of the PMX Series Multipurpose Digital Meter Equipment Monitoring

Systems. This manual is an overview of the system and references the specific

component manuals. User manuals are provided with the system for all

configurable internal components.

Description

The PMX Series Systems monitors a machines condition based on its level of

vibration. The PMX1000 & 2000 Series Systems will display the vibration levels

from one or two signal conditioners or loop power vibration sensors. The

systems can be integrated into a circuit to shutdown a machine when preset

vibration levels are reached. The systems detects high vibration energy being

sensed by the input sensors and actuates relays based on alert and alarm set

points. The system will indicate the instantaneous vibration levels and relay

status at each channel through the display meters.

The PMX3000 Series Systems displays the overall value of one or two field

mounted LP400 Series Sensors and provides the dynamic output from panel

mounted BNC Jack connectors for portable analysis. This system can also be

integrated into a circuit to shut down a machine when preset vibration levels are

reached.

PMX1000/2000 Model Selection

The PMX1000/2000 Series System has different options available, below is a

guide to help select which PMX1000/2000 Series System fits your specific

requirements. (Figure 1)

PMX3000 Model Selection

The PMX3000 Series System has different options available, below is a guide to

help select which PMX3000 Series System fits your specific requirements.

Mounting

The system is contained within a standard fiberglass, NEMA 4X rated. Mounting

brackets are built into the enclosure for wall-mounting the enclosure. (Wall

anchoring screws are not included).

Note: CTC does not recommend putting holes in the top of the enclosure

due to access and moisture concerns.

Mounting

Brackets Ground Lug

MNX10037 REV A

Ensure the shield ground wire is connected to earth ground.

Note: The customer is required to supply from ground to shield ground lug,

located on the outside of the enclosure. (Figure 3)

If you are running conduit to your enclosure, ensure the conduit cable entry

enters from the bottom of the enclosure when mounted.

Note: To ensure moisture will not flow into the enclosure, a hole should be

drilled at the lowest point in the conduit to provide drainage for any

moisture.

For PMX1000/2000 Series Systems, all input wiring is connected to the PRO

Multipurpose Digital Meter Equipment Monitor through removable screw terminal

blocks. For the PMX3000 Series Systems, all input wiring is connector to the

provided terminal block mounted on the back panel of the enclosure. Cord grips

(1 per ch.) or a ½” conduit fitting is provided for sensor input wiring.

For all PMX Series Systems, cable exit is offered through a ½” conduit fitting.

NOTE: If there is no sensor wired, the Output Display will read low or

negative values. Be sure to power the system AFTER the sensor has been

connected.

NOTE: If the display fails to output a value after power has been turned on

and the sensor has been wired, turn off the unit, wait several seconds and

then reapply power. The internal electronics require some time to ramp up

and settle before they are fully operational.

Electrical Connections

Power entry for the PMX Series Systems is provided by a ½” conduit fitting. 85-

265VAC is required to power the unit through the terminal in the center of the

enclosure. See Figure 6 for power wiring.

WARNING: Risk of Electrical Shock (Figure 6).

Power Wiring

The PRO Multipurpose Digital Meter Equipment Monitor(s), PD765(s), will be

wired for power in the factory for all PMX Series Systems. The customer is

responsible for wiring the relays and input signals.

Figure 7 – Power Entry

PMX1000/2000 Series System Sensor Wiring

Input wiring should be wired directly to the back of the display relays as

described in the PD765 Pro Universal Input Meter Instruction Manual.

Input wiring should be wired to the provided terminal block on the back panel.

Unlike the PMX1000/2000 Series Systems, the PMX3000 Series System is

factory set as 4-20mA Input and Scaled at 0-1 IPS Amplitude.

Configuring Relays

The input to the internal controller comes from a vibration transmitter. They are

built with a specific full scale range and frequency band. Full scale range of the

transmitters must be known in order for the controllers to display the correct

vibration value. The transmitter will not display any vibration energy present at

frequencies outside the filtering range. Manual adjustments to the Signal

Conditioner may be required. Refer to PRO Signal Conditioner User Manual for

specific instructions on calibration and operation.

The monitoring channel provides 2 relay outputs. The system comes from the

factory with a specific vibration range in IPS or mm/s. To configure the relay set

points, this range must be known. It is recommended that baseline and typical

alarm values of vibration are also known before setup is attempted. The relays

provided by the internal controller are highly configurable. Refer to PD765 User

Manual for detailed programming instructions.

All of the following parameters can be adjusted:

Relay Action – Automatic, Latching, Auto + Manual Reset, Latch with

Clear.

Relay Operation – Set and Reset points (Hysteresis), On and Off time

Delays.

Section III

Operation

Example Full Scale 0 – 1.0 IPS, Frequency Band 10 – 1000 Hz.

At 0 IPS, 0 Volts flow from the transmitter to the controller

At 0.50 IPS, 2.5 Volts flow from the transmitter to the controller.

t 1.0 IPS, 5 Volts flow from the transmitter to the controller.

MNX10037 REV A

Analog Output

The analog 4-20 mA signal represents the amount of vibration energy present at

each channel based on the transmitter’s full scale. I.E. a 12 mA signal from a 0-

2.0 IPS transmitter represents a vibration level of 1.0 IPS.

Obtaining the 4-20mA output from the controller may require manual adjustment

of the SC Transmitters. Refer to PRO SC Transmitter user manual for specific

instructions.

Refer to PD765 User Manual for detailed programming instructions.

Example Setup 1:

A full scale range of 0 – 1 IPS has been specified. Baseline Vibration on the

machine to be monitored is 0.18 IPS-pk. Alarm and Shutdown levels of

vibration are specified as 0.35 IPS-pk and 0.65 IPS-pk respectively, reset

points are specified as 0.30 IPS-pk and 0.60 IPS-pk. Using the provided

PD765 Process Controller Manual; Select relay operation and action desired,

for this example we will have LOC, Latching Operation with Clear relays.

Then program “Set 1” as 0.35 and “Set 2” as 0.65, then program reset points,

“rST 1” as 0.30 and “rST 2” as 0.60. After relays have been programmed,

scaling must be set. For this example, we will use a 0-5 Volt input with a 0-1

IPS display. Program “inP1” as 0.00, then “diS1” as 0.00, then “inP2” as 5.00,

then “diS2” as 1.00. This will let us have an input of 0 Volts, display of 0.00

IPS and at an input of 5 Volts, 1.00 IPS will be displayed by the meter. The

system will now actuate the LOC Relay (Relay 1) when the vibration level

reaches 0.35 IPS-pk and another LOC Relay (Relay 2) when the vibration

level reaches 0.65 IPS-pk. In order to reset the LOC relays, the vibration level

must fall below the reset point of 0.60, then press the ACK for relay 2 and

once the vibration level falls below 0.30, press the ACK to reset relay 1.
