Assembly and Installation
The PID module must be configured internally and wired externally to
suite the conditions under which the module will be used. Module and
power supply specifications are listed at the end of this chapter.
The PID module is a dual-slot module. The left front panel contains three
LED indicators, the right front panel contains a write-on label that can be
used to record the voltage or current range and the most recent date of
calibration. An 18 terminal field wiring arm is connected to the lower
right front of the module for I/O and power connections. The label on the
right cover plate identifies the terminals of the field wiring arm.
Diagnostic Indicators
Front panel indicators (Figure 2.1) allow an operator to observe the
operating condition of the module. The indicators will be on, off or
flashing (Table 2.A).
