collects in the drain valve and the level slowly rises which
is detected by the sensor. When the condensate reaches upper
level the controller signals the valve to open. The condensate
now drains. When the condensate level reaches low level
the controller switches off valve and stops the draining.
controller routinely checks for health of the system and
can detect probe or valve failure and take action. There
are 3 LED displays which indicate all these. There is
also Test/ Manual override button. The condensate level
sensor is of capacitance type. This makes it work on all
types of condensates e.g. water, water+oil, water+oil+dust
the condensate is not discharged due to valve failure
then the condensate level will not reach lower limit.
The controller energises the solenoid coil for 8 secs.
and waits for 2 mins. It repeats the timed cycle of 8
secs. ON and 2 mins. OFF, 4 times. If condensate level
does not reach the low limit then the controller activates
the alarm mode and alarm mode LED glows. In the alarm
mode the controller works on a timed cycle. The controller
automatically reverts to normal mode when the problem
