OPERATION AND FAILURE INDICATION
The pressure switch display indicates System Pressure,
Set Point, and Switch Output status. Additionally,
failures are indicated for short circuit or self check
errors.
Steady LEDs indicate the actual pressure within 10%.
The blinking LED indicates the Set Point pressure
within 10%.
To display the Set Point within 1%, press the Set S
button once.
To display the Reset Point within 1%, press the Set R
button once.
A short circuit or current overload error is indicated by
all green LEDs blinking. Remove the short circuit.
Self check errors are indicated when the five leftmost
LEDs are blinking. Contact the factory for assistance.
NOTE: High pressure surges (spikes), can be caused
by the opening and closing of valves, and may be
present in a fluid system. These pressure spikes are
short in duration (<5 ms) and can damage the switch if
they exceed the pressure switch over pressure limit.
