6.2 - Installation Procedure
•
The XLE/XLT utilizes a clip installation method to ensure a robust
and watertight seal to the enclosure. Please follow the steps below
for the proper installation and operation of the unit.
•
This equipment is suitable for Class I, Division 2, Groups A, B, C and
D or non-hazardous locations only.
•
Digital outputs shall be supplied from the same source as the
operator control station.
•
Jumpers on connector JP1 shall not be removed or replaced while
the circuit is live unless the area is known to be free of ignitable
concentrations of flammable gases or vapors.
1.
Carefully locate an appropriate place to mount the XLE/XLT. Be
sure to leave enough room at the top of the unit for insertion and
removal of the microSD™ card.
2.
Carefully cut the host panel per the diagram, creating a 92mm x
92mm +/-0.1mm opening into which the XLEe/XLTe may be
installed. If the opening is too large, water may leak into the
enclosure, potentially damaging the unit. If the opening is too small,
the OCS may not fit through the hole without damage.
3.
Remove any burrs and or sharp edges and ensure the panel is
not warped in the cutting process.
4.
Remove all Removable Terminals from the XLE/XLT. Insert the
XLE/XLT through the panel cutout (from the front). The gasket
must be between the host panel and the XLE/XLT.
5.
Install and tighten the four mounting clips (provided in the box)
until the gasket forms a tight seal (
NOTE: Max torque 0.8 to 1.13 Nm
or 7-10 in-lbs)
6.
Reinstall the XLE/XLT I/O Removable Terminal Blocks. Connect
communications cables to the serial port, USB ports, Ethernet
port, and CAN port as required.
7 ANALOG IN TRANZORB FAILURE
A common cause of Analog Input Tranzorb Failure on Analog Inputs Model
2, 3, 4 & 5: If a 4- 20mA circuit is initially wired with loop power, but without
a load, the analog input could see 24VDC. This is higher than the rating of
the tranzorb. This can be solved by NOT connecting loop power prior to load
connection, or by installing a low-cost PTC in series between the load and
analog input.

Digi-Key BC2316-ND
The XLE/XLT uses a replaceable non-rechargeable 3V Lithium coin-
cell battery (CR2450) to run the Real-Time Clock and to keep the
retained register values. This battery is designed to maintain the clock
and memory for 7 to 10 years. Please reference MAN0878 providing
instructions on how to replace the battery.
