Auxiliary inputs
The auxiliary inputs are intended for sensing the open or closed condition of
additional system components and sensing switches. Typically the auxiliary
inputs are expected to be connected to float switches for sensing water levels.
The active auxiliary input circuits are selectable with the DIP switches. Each
auxiliary input circuit has a jumper selection for normally closed or normally open
operation. The sensing signal at the auxiliary input terminal block is a current
limited 12VAC. Note: Auxiliary contact three will is interlocked with the pump
relay and will deactivate the pump circuit. Do not use this contact for high water
floats in pump tanks.
Indicator LEDs
There is a blue power indicator LED that is lit when power is applied and the
microcontroller is running. There is a one red LED for indication of aerator over or
under current conditions. There are three red LEDs for indication of input error
conditions on the auxiliary inputs. In normal operation, with no error conditions
present, only the blue power indicator LED will be on. Auxiliary alarm circuits
should be properly labeled on the wiring diagram or control panel cover.
Alarm buzzer
The alarm buzzer sounds when an error condition exists. There is circuit board
provision for an externally mounted or alternate model buzzer. When power is
initially turned on, the buzzer will sound for ½ second to confirm that the buzzer
is operational. For purposes of testing or servicing, the buzzer can be silenced
for alarm conditions by DIP switch setting.
Reset switch and master reset switch
The user accessible reset switch has dual functionality. If no alarm condition
exists, and the reset switch is held down for at least two seconds, the
microcontroller will perform a self-reset. If an alarm condition has been triggered,
the reset switch will clear the alarm state. However, if the error condition is still
present, the alarm may immediately re-trigger. After the third reset press with a
continuing alarm condition, the buzzer will be silenced, but the LED error
conditions will not be cleared and no further operation is possible until the panel
is reset by the master reset switch or by removal and reapplication of main
power. The circuit board mounted master reset switch causes a microcontroller
reset.
