Water Switch System Operation
Description of Controls and Indications in Controller:
1) Manual – Off/Reset – Auto Switch
Off/Reset Mode:The controller function is Off and pump will not run in this mode. Also used
to Reset when Dry Run Tripped.
Auto Mode:The controller function is in automatic mode and the motor On/Off and
tank filling function will take place automatically depending upon the
tank level, voltage conditions etc.
Manual Mode:The controller function is over ridden and pump control output is
continuously on irrespective of the water level in the overhead tank,
sump, and well. The low voltage and high voltage and Dry Run Protection
for the motor will not be available in this mode.
2) Indicators:Pump On/Output On: Indicates the Controller output is “ON” thus the
pump is ON
Dry Run: Indicates Controller Tripped (Auto Mode) due to
Dry Run (or Indicates Running Dry in Manual
Mode)
High Voltage: Indicates the mains voltage is very high (motor is
“Cut Off” if the controller is in “Auto” mode)
Low Voltage: Indicates the mains voltage is very low (motor is
“Cut Off if the controller is in “Auto” mode)
Sump Empty: Indicates Sump/Well is empty.
Tank Full: Indicates the overhead tank is full.
Auto :Indicates the control function is in automatic mode
Operation:
After powering up the Controller, put the switch to Auto position if you
would like the tank filling operation to be controlled automatically. This is
the normal operation position of Controller. If DR Switch is fitted, the
system will monitor water delivery for 1-2 minutes and if water did not flow
within this time the Controller will initiate Dry Run trip.
Dry Run Reset Function – If Dry Run occurred find out the reason and repair
as required. Turn Controller Switch to Off/Reset position to Reset and then
Switch to Auto position for Normal operation.
If the motor pump is to be switched on continuously, even if the over
head tank is full or Sump is empty or mains voltage is high or low etc.,
the switch shall be in Manual position. Please note that there will not be
any protection such as high voltage, low voltage or Dry Run to the motor if
the manual mode is selected. The manual function will work within the
operating voltage range of the controller as mentioned in the
specification. If the motor is required to be switched off then keep the
switch in the Off/Reset position. Motor will not run when switch is in the
Off/Reset position.
Timer contact will be closed for 2-4 seconds at the time of switching on the
motor
