I) Overview
General
The CR500 is a microprocessor based circle chart recorder. Programmable alarm options
combined with “ease of setup” provide the flexibility required for multiple recording
applications. This manual will cover both ink type and thermal print versions.
The CR500 is the first recorder to “self document” setup configuration during initial
setup and can operate using standard or competitive charts. The battery backup option (on
ink type units) provides up to 48 hours of recording in the event of power loss, thereby
providing an additional degree of protection for customer processes. A green status LED
indicates battery condition; see Battery Backup (Page 17).
The Thermal print version offers a single chart inventory for all recording needs. “Print
your own” chart technology includes real time trend and printed time and date directly on
the chart. The Thermal Recorder provides dual channel recording as standard. Each
channel is configurable for universal inputs. The unit can easily be configured, in field, to
single channel via keypad.
The unit is powered by 110/220VAC, 50/60Hz. Programmable inputs for thermocouple
types J, K, T, R, B and S as well as 4-20mA are standard. Optional alarm relays are
available and are programmable for low, high or band operation. The green LED
indicates unit is powered.
A unique setup chart provides the user with an “on the spot” manual. This setup chart
will also self-document the current setup for quick review by an operator.
High accuracy, maximum flexibility, fast response, and a simple user interface are the
main benefits of the CR500 recorder.

II) Installation
Dangerous voltages capable of causing death are sometimes present when wiring
the instrument. Before installation or beginning any troubleshooting procedures, the
power to all equipment must be switched off and isolated. Units suspected of being at
fault must be disconnected and removed to a properly equipped workshop for testing and
repair. Component replacement and internal adjustments must be made by qualified
personnel only. This recorder operates on 110 or 220 (50-60 Hz), be sure line voltage is
OFF before connecting recorder.

To minimize the possibility of fire or shock hazards, do not expose this instrument
to rain or excessive moisture.
Do not use this instrument in areas under hazardous conditions such as excessive
shock, vibration, dirt, moisture, corrosive gases or oil. The ambient temperature of the
areas should not exceed the maximum rating specified.

Mounting
Make panel cutout to dimension shown in Figure 2.0.
Install both mounting clamps and insert the case into panel cutout.
Figure 2.0 Mounting Diagram
Case Location
Upon unpacking, find a suitable location to mount the recorder before wiring power to
the unit. Refer to Wiring Precautions (Page 8). After the recorder has been connected to
the main AC power supply, connect the battery (optional) to the battery strap and place
the battery in its holder.
Select a location that is well lighted, free from dust, dirt, or corrosive fumes. The
instrument should not be located near any sources of heat or be subject to sudden or
extreme temperature changes. It should be mounted on a rigid support that is not subject
to vibration. Refer to Figure 2.0 for recorder case dimensions.

Wiring Precautions
1) Before wiring, verify the label for correct model number and options. Switch off
the power when checking.
2) Care must be taken to ensure that maximum voltage rating specified on the label
is not exceeded.
3) It is recommended that power of these units to be protected by fuses or circuit
breakers rated at the minimum value possible. All units should be installed inside
a suitably grounded metal enclosure to prevent live parts being accessible from
human hands and metal tools.
4) All wiring must conform to appropriate standards of good practice and local
codes and regulations. Wiring must be suitable for maximum voltage, current,
and temperature rating of the system.
5) Take care not to over-tighten the terminal screws.
6) Unused control terminals should not be used as jumper points as they may be
internally connected, causing damage to the unit.
7) Verify that the ratings of the output devices and the inputs are not exceeded.
Refer to Specifications (Page 27).
8) Electric power in industrial environments contains a certain amount of noise in
the form of transient voltage and spikes. This electrical noise can enter and
adversely affect the operation of microprocessor-based controls. For this reason,
we strongly recommend the use of shielded thermocouple extension wire, which
connects the sensor to the unit. This wire is a twisted-pair construction with foil
wraps and drains wire. The drain wire is to be attached to earth ground at the
sensor end only.
Power Wiring
The unit is supplied to operate at 110/220VAC 50/60Hz. Check that the installation
voltage corresponds with the power rating indicated on the product label before
connecting power to the unit.
The recorder uses AC power when it is operating normally. The battery back-up option
on ink recorders will allow the recorder to operate for approximately 48 hours in case of a
power loss. The AC input can be fused with a 250VAC, .5 Amp fuse.
In order to connect the recorder to the main AC power, you must first gain access to the
PC board that is mounted to the back of the chart plate. Your recorder will have a hinged
chart plate held in place by two (2) screws located on the right hand side of the chart
plate. Remove these two screws and open the hinged chart plate. If you are not sure how

to access the back of the chart plate, please contact GLOBAL WATER
INSTRUMENTATION before continuing.
Figure 2.1 Power Supply
The AC power connections are made to the 4 pin terminal block located on back side of
platen. All AC and ground wires must be a minimum of 16 AWG.
Refer to Figure 2.1 for proper connection to the main AC power.
Earth Ground must be connected at ground lug provided. See Figure 2.1
This equipment is designed for installation in an enclosure which provides adequate
protection against electric shock. Grounding of this recorder must meet national and local
codes. Ground wire should be Color coded GREEN or GREEN with a YELLOW stripe.
Local requirements regarding electrical installation should be rigidly observed.
Proper steps should be taken to prevent unauthorized persons from gaining access to the
power terminals.

4-20mA Input Wiring Pen1/Pen2
Transmitters and sensors with 4-20mA outputs can also be connected to the recorder as
shown in the following input wiring figures (Figure 2.2). No voltage is provided to power
these sensors and must be supplied externally or an optional sensor power supply can be
purchased from Global Water.

Thermocouple (TC) Installation Guidelines
Proper sensor installation can eliminate many problems in a control system. The probe
should be placed so that it can detect any temperature change with minimal thermal lag.
In a process that requires fairly constant heat output, the probe should be placed close to
the heater. In a process where the heat demand is variable, the probe should be close to
the work area. Some experiments with probe location are often required to find this
optimum position.
Proper sensor type is also a very important factor to obtain precise measurements. The
sensor must have the correct temperature range to meet the process requirements. In
special processes, the sensor might need to have different requirements such as leakproof, anti-vibration,
Standard thermocouple sensor limits of error are 4° F (2° C) or 0.75% of sensed
temperature plus drift caused by improper protection or an over-temperature occurrence.
This error is far greater than controller error and cannot be corrected at the sensor except
by proper selection and replacement.
In order to connect the probe input device to the recorder, you must first gain access to
the PC board that is mounted to the back of the chart plate.
A ferrite bead has been included to provide additional protection for electrical “Noise”
sensor signal wires can pick up. See drawing below for correct installation of this device.

CAUTION! DO NOT TOUCH the terminals of the transformer while the
recorder is connected to the main AC power supply. To avoid the risk of possible electric
shock, unplug or disconnect the recorder from the main power supply before attempting
to open the recorder. If the recorder is installed with the battery back-up option,
disconnect the 9 Volt battery to avoid damaging the recorder and draining the battery.
Your recorder will have a hinged chart plate held in place by two (2) screws located on
the right hand side of the chart plate. Remove these two screws and open the hinged chart
