Unpacking Your System

Some suggestions for unpacking your system are provided below.

•Please unpack each package of the shipment carefully. Be sure to remove all items. Small

items such as cables and batteries are easily overlooked.

•Compare the total received shipment contents with the packing list. Contact Telog if items

are either missing or different from the packing list.

•Save the shipping cartons, boxes, etc. They can be reused if you need to return a recorder

for service.

•Carefully inspect all items for shipping damage.

If you received a sensor or transmitter with your recorder, inspect the sensing elements by

unscrewing the black plastic tip of the sensor or transmitter and visually inspect the

crystal diaphragm for cracks or other obvious physical damage, then replace the tip.

•Do not attempt to install or use any damaged item. If items were damaged in shipment,

contact the shipper for assistance.

Cleaning Your System

Information for routine cleaning of Telog recorders is provided here. Additional information

for cleaning and decontaminating e-series recorders if they are exposed to known or potential

health hazards is described in Section 3.

Note: Telog reserves the right to withhold service from any product until proper

cleaning and decontamination have been accomplished and certified.

To perform routine cleaning, wipe the enclosure of the recorder with a water-dampened cloth.

If needed, use a mild detergent, then wipe the detergent with a water-dampened cloth. Wipe

excess water from around the connectors. Allow the water to evaporate thoroughly before

returning the recorder to service.

Section 1.

Telogers:

R-3000

Series

Recorders

Overview

The Telogers data acquisition system is designed to perform automatic data collection from

remote locations. A minimum system configuration consists of at least one R-3000 series

(Teloger) recorder, Telogers for Windows (S3-PC) support software running on a personal

computer and a data transfer cable (C-21ATC). A more common system configuration

consists of several (five, 50, or even 300) Telogers sharing Telogers for Windows.

There are several models of Teloger recorders in the R-3000 recorder series. The model

number identifies the number of independent channels for data collection. Appendix A and

Table 1-1 provide information on each model in the R-3000 series, sensors and accessories for

a Telogers system.

Each Teloger consists of a circuit board packaged in a bent metal enclosure for panel

mounting. The recorder’s face-plate contains information on connections for power, telephone

and signal inputs. Optional NEMA 4X enclosures are available to fit your specific application

requirements.

Program each R-3000 using Telogers for Windows. The R-3308 recorder channels are

completely software programmable. The R-3307 and R-3314 recorders have hardware

switches that set the analog channels to collect either current or voltage information. The

R-3303 recorder does not have analog channels. Information on setting the hardware switches

is provided later in this section.

If your R-3000 Teloger has the optional M-324 modem module or an external modem, you

can reprogram and collect data using remote communications. If the recorder does not contain

the module or an external modem, use the data transfer cable for local (direct) connection to

the computer running Telogers for Windows (S3-PC) to program and collect data.

Refer to the Telogers for Windows User Guide for information on setting up, programming

and collecting and analyzing data from an R-3000 recorder.

Analog Channel Inputs

Input Types

The analog channels on the R-3307and the R-3314 have hardware switches you must set to

measure either voltage or current, then use Telogers for Windows to select the same input.

Four of the R-3308 analog channels can be set for current loop, voltage (with pulsed

excitation) or RTD input. An fifth analog channel is dedicated to ambient temperature input.

Voltage

Each voltage input terminal appears as a 1MΩinput to the recorder’s ground and allows for

differential measurement of voltage between the + and – terminals in the presence of common

mode voltage. The maximum common mode voltage that can exist at each input without

introducing measurement error is a function of the range and is described in Table 1-3 and

shown in Figure 1-1.

Table 1-3. R-3000 Analog Voltage Inputs

Selected input range Maximum common mode range

1V or less ±4V

2V or more ±40V

Current loop

Current measurement is performed by measuring the voltage across an internal shunt resistor

between the + and – input terminals. This resistance produces a burden voltage to the current

loop as described in Table 1-4.

The shunt resistance is comprised of a series precision resistor and a positive temperature

coefficient (PTC) resistor. If the input current exceeds 80mA, the PTC resistor will increase

resistance rapidly to protect the precision resistor. When external excitation is removed, the

PTC resistor returns to its original resistance value. When in current mode, the maximum

voltage that can be applied across the input terminals without causing damage to the precision

shunt is 30V. Refer to Figure 1-2 for schematics.

1 mA range 20 mA range

R-3307, R-3314 200ohms 0.2V 4V

R-3308 100ohms 0.1V 2V

RTD

The R-3308 recorder supports 3-wire and 4-wire 100Ωplatinum RTDs with α= 0.00385.

Three-wire RTDs require the addition of a jumper between the excitation and + terminals. The

recorder automatically performs pulsed excitation, lead-wire resistance correction and

linearization for RTD inputs. Refer to Figure 1-3 for schematics.

Thermocouple

The R-3308 recorder supports five types of thermocouples: J, K, T, E and R. Thermocouple

inputs are polarized. The recorder automatically performs cold-junction compensation and

linearization for thermocouple inputs. Refer to Figure 1-4 for a schematic.

Ambient Temperature

The R-3308 recorder can measure ambient temperature (-20 to +80°C) on channels 1–5 with

the Telog ambient temperature probe (AT-4). Channel 5 is dedicated to this measurement.

Refer to Figure 1-5 for schematics.

Excitation

The R-3308 analog channels provide pulsed excitation to power external sensors and

transmitters on all channels. Pulsed excitation permits the recorder to excite or power certain

external sensors and transmitters to minimize power consumption, specifically when the

sensor and recorder are powered by batteries. For example, a 4-20mA transmitter, which may

consume as much as 240mW if continuously powered, may consume, on average, only 240µW

(1000 times less) if the measurement can be taken once every 10sec with an excitation period

of 10ms.

If external power is available to the recorder and sensor, it is not necessary to use the pulse

excitation feature. (Standard connection diagrams, when excitation is not employed, are

provided in Figures 1-1 and 1-2.)

The excitation is user-selectable as 5V, 12V, or 1ma with a programmable duration from 5 to

400ms. The maximum current for 5V and 12V excitation is 20mA. The maximum output

voltage for 1ma excitation is 1V.

Some applications using pulsed voltage excitation are described in the list below. The

recommended connections for each application are shown in illustrations in Figure 1-6.

•A 2-wire current loop transmitter. Note that a 12V excitation pulse provided to a remote

current loop transmitter results in only 10V available for the transmitter since as much as

2V will be dropped across the R-3308 current shunt resistance.

•A 3-wire voltage sensor/transmitter where the signal return is also the negative supply of

the sensor. You must supply a connection between the recorder terminal and the ground

terminal.

•A resistance bridge network in the range of 250 to 50,000 ohms.

•A 4-wire voltage sensor/transmitter where the output signal is independent of the negative

supply to the sensor.

•A 3-wire potentiometer in the resistance range of 250 to 50,000 ohms with 5V excitation.

We recommend 5V excitation. The system determines the wiper position as a percent of

full-scale travel.
