Function:
The UA-XD is a microprocessor controlled single or dual trip. It is easily field configurable to operate
in a large number of different modes. Each relay contact output is individually configurable to the
following modes of operation: High/Low Trip , Normally Energized / De-energized. Additionally, both
relays can be made to operate from the same input to give two levels of alarm for a single input.
A delay feature allows a 0-60 sec. adjustable ON delay to be added to the trip function in order to
screen out intermittent and erroneous alarms. If the delay function is activated, the input must be
greater than the setpoint for the time specified by the delay before the relay will activate. There
is also a combined ON and OFF delay function which, in addition to delaying the relay 'turn-on' time,
delays the relay'turn-off' time.
