4.2 Specifications
4.2.1 Operating temperature
Operating temperature range: 0 to 55 C (-40 C to 70 C
storage). Relative humidity zero to ninety (0-90) percent (non-
condensing).
4.2.2 Power source
The control voltage range of operation on the standard unit
is
+
15% to -35% rated voltage, and 50 or 60 hertz ±3 hertz,
25 VA.
Range for 115 VAC is 75 V min. to 132 V max.
Range for 230 VAC is 150 V min. to 265 V max.
These voltage ranges should not be exceeded or erratic
operation may result.

NOTE: Since the potential input for the power factor
detection is derived from the control power input (V1
and
V2,l,
it is imperative that the voltage input be
taken from the two proper motor phases. See Typical
Elementary Diagram (Figure 10) to determine proper
phases.
4.2.3 Relay outputs
The three relay outputs (TRP, FAR, and FCX) have the
following contact ratings:
120 VAC
240VAC

The following is a description of the relay outputs.
1. TRP -
Trip Relay. This relay is normally energized
and drops out on loss of power or when the module senses
an abnormal condition.
2. FAR -
Field Application Relay. This relay picks up at
the proper time to apply dc to the motor field.
