4.5 THERMOCOUPLE INPUTS - The terminal module accepts industry standard type “J” or “K”
thermocouples on inputs 37 and 40-45. Automatic cold junction compensation is built-in. The
units can be configured to
E
F or
E
C. Both a high and low setpoint is associated with each
channel. The monitor can read type J thermocouples between

5.0 MOUNTING
5.1 DISPLAY MODULE - Mount the Display Module inside a control panel or to a suitable flat
surface so that the display is at a convenient viewing height. A drilling template and mounting
dimensions are provided. NOTE: Avoid mounting the unit with the LCD display facing direct
sunlight. The display operating temperature range is
!
31
E
F to +176
E
F (
!
35
E
C to +80
E
C).
5.2 POWER SUPPLY MODULE - Mount the Power Supply Module in the panel either on the
bottom or the side of the main panel. The Power Supply Module is made to be rail mounted
onto commercially available 32 or 35 mm DIN mounting rails. It is also made to plug directly
into the Terminal Module using the DB-25 connectors and is held together with screws and
screw locks. Two end brackets P/N 610751 should be used to keep the modules from sliding
off the ends of the mounting rail.
As an alternative, the Power Supply Module and the Terminal Module can be mounted
separate from each other on the DIN mounting rails but in the same panel; in this case, a DB-
25 male/female cable such as P/N 693115-1 is used to electrically connect these modules.
The operating temperature range of the Power Supply Module is

5.3 TERMINAL MODULE - Mount the Terminal Module in the panel either on the bottom or the
side of the main panel. The Terminal Module and Power Supply Module are made to be rail
mounted onto commercially available 32 or 35 mm DIN mounting rails. The Terminal Module
is made to plug directly into the Power Supply Module using the DB-25 D-Sub connectors and
held together with screws and screw locks. Two end brackets P/N 610751 should be used
to secure the modules from sliding off the ends of the mounting rail. The Terminal Module and
the Display Module are electrically connected with a DB-25 male/female cable, 693115-x
series or equivalent. The operating temperature range of the Terminal Module is

5.4 PRESSURE TRANSDUCER - Mount the pressure transducer in the panel or in a manifold or
tube off of the engine. Do not expose the pressure transducer to temperatures above 221
E
F.
(105
E
C).
IMPORTANT:
Pressure transducers will withstand overloads as high as 1.5 times rated
pressure. If the overload rating is exceeded, failure may occur. Pressure fluctuations occur
in most reciprocating systems; pick the transducer with a rating high enough to prevent
overload by peak pressures of pulsations. It is recommended that a pressure snubber be
used which will reduce the peak pressure applied to the transducer. The life of the transducer
will be extended with the use of a snubber or pulsation dampener.
5.5 TEMPERATURE TRANSDUCER - Mount the temperature transducer in a thermowell on the
engine or machine. The actual sensor is located at the bottom of the transducer body; to
ensure accuracy, the tip of the probe should be surrounded by the measured media.
IMPORTANT:
Do not exceed the absolute maximum rating of the transducers, 350
E
F
(176
E
C) for the 691202/203-300 or 450
E
F (232
E
C) for the 691212/213-450. Care should be
taken to protect the wiring and connectors from contact with hot surfaces.
