1Safety Instructions
This document contains important information, which should be
kept at all times with the instrument during its operational life. Other
users of this instrument should be given these instructions with the
instrument. Eventual updates to this information must be added to
the original document. The instrument should only be operated by
trained personnel in accordance with these instructions and local
safety regulations.
Acceptable Operation
This instrument is intended only for the measurement of
temperature. The instrument is appropriate for continuous use. The
instrument operates reliably in demanding conditions, such as in
high environmental temperatures, as long as the documented
technical specifications for all instrument components are adhered to.
Compliance with the operating instructions is necessary to ensure the
expected results.
Unacceptable Operation
The instrument should not be used for medical diagnosis.
Replacement Parts and Accessories
Use only original parts and accessories approved by the
manufacturer. The use of other products can compromise the
operational safety and functionality of the instrument.
Instrument Disposal
Disposal of old instruments should be handled
according to professional and environmental
regulations as electronic waste.

Safety Instructions

Operating Instructions
The following symbols are used to highlight essential safety
information in the operation instructions:
Helpful information regarding the optimal use of the
instrument.
Warnings concerning operation to avoid instrument
damage and personal injury.
The instrument can be equipped with a Class 2 laser.
Class 2 lasers shine only within the visible spectrum at an
intensity of 1 mW. Looking directly into the laser beam
can produce a slight, temporary blinding effect, but does
not result in physical injury or damage to the eyes, even
when the beam is magnified by optical aids. At any rate,
closing the eye lids is encouraged when eye contact is
made with the laser beam. Pay attention to possible
reflections of the laser beam. The laser functions only to
locate and mark surface measurement targets. Do not aim
the laser at people or animals.

Safety Instructions
GP Series Rev. F 10/2011 3
Pay particular attention to the following safety instructions.
Use in 110 / 230 VAC electrical systems can result in
electrical hazards and personal injury if not properly
protected. All instrument parts supplied by electricity
must be covered to prevent physical contact and other
hazards at all times.

Description
4 Rev. F 10/2011 GP Series
2Description
The GP monitor consists of printed circuit boards, A/D converters,
microprocessor, control switches, and power conditioners, all
mounted in a 1/8 DIN panel-mount NEMA-12 (IP 54) enclosure. The
GP monitor accepts inputs from any 0-5V and 4-20mA devices, which
allows it to be used as a panel meter for many applications. Other
settings allow the GP to act as a temperature monitor for Raytek fixed
infrared sensors like GPR, GPS, CI3, CM, TX and XR and for other
temperature gathering devices. The GP Monitor also accepts various
types of thermocouple inputs. It provides two programmable
setpoint alarm signals (open collector or relay) and one of two types
of analog output: 4-20 mA output or thermocouple output. (Factory
default is 4-20 mA output.)

3.2 Mounting Instructions
The GP monitor meets NEMA-12 (IEC529, IP54) requirements (front
panel only) for protection of the electronics when mounted properly.
It should be surface mounted using the flanges and holes provided
and mounted in such a manner to allow the free flow of air around
the unit. Ambient temperatures should be kept within the range of
0 to 50°C (32 to 120°F).
Mount the monitor as far away as possible from potential
sources of electromagnetic interference!
Complete the following steps to mount the GP monitor to a panel, see
also Figure 2:
1. Cut a hole 45 mm high by 92 mm wide (1.8 in by 3.62 in) in the
panel.
2. Slip the gasket over the rear of the monitor and then back the
monitor into the hole from the front side of the panel. (Mounting
bracket and cosmetic frame are available as accessories.)
3. Attach the fixing clamps to both sides of the monitor. Make sure
the tab is secure in the hole on both sides.
4. Fix the monitor with the clamp screws!

Figure 2: Mounting the Monitor
5. Secure the monitor to the panel by tightening both fixing clamp
screws until the flanges are snug against the back surface of the
panel.
6. Connect the terminal cable as described in the following section.
7. After you complete the electrical installation, secure the rear
cover to the back of the monitor.
Do not operate with rear cover removed because of
electrical shock hazard!
3.2.1 Mounting Bracket Accessory
A mounting bracket is available as an accessory. To mount a GP
Monitor to a wall, post, column, or other flat surface, complete the
following steps:
1. Insert the rear of the monitor through the bracket’s opening so
the bottom of the monitor rests on the bracket surface. Make sure
the gasket is in place Figure 3.

2. Insert the Tab on the side of each fixing clamp (one per side) into
the hole on the side of the monitor housing and hold them. You
might need to loosen the fixing clamp screws first, see Figure 4.

4. You will need to attach wires to the monitor’s terminals and
attach the rear cover before mounting the bracket onto a surface.
(Refer to the manual for wiring instructions for your particular
device.)
5. Use 3 appropriately sized screws or bolts to fasten the bracket
onto your work surface.
This completes the monitor bracket accessory installation.
3.2.2 Cutout Template and Cosmetic Frame
If you are mounting your monitor into a panel, this plastic frame can
be used as a template for determining the proper dimensions for
your panel cutout. To use, hold or tape the template against the panel
at the location where you want to mount the monitor, and mark
around the inside edges, see Figure 5.
Once you cut the panel, you can use this template as a frame to hide
scratches or small voids on the panel that might have been created
during the cutting process.
To install, simply insert the frame between the monitor bezel and
mounting gasket prior to inserting the monitor into the panel.
