For Two Point / Pump Control Logic
•
Unscrew the cover and ensure that all DIP switches
are in OPEN position as shown in Figure 18. Make

Uncover Delay
When the application material uncovers Casper’s probe,
the changeover of the output can be delayed by a pre-
determined time. This time is called UNCOVER Delay. For
a different value of uncover delay, the number of blinks can
be adjusted as per requirement.
The STATUS LED will start blinking RED if the switch point
is achieved. It will blink for the number of seconds for which
the uncover delay is set.
Note:
Set the value of UNCOVER DELAY between
1-25 secs.
12.1
For Single Point Switching
•
Unscrew the cover and ensure that all DIP switches
are in OPEN position as shown in Figure 18. Make
sure that STATUS LED is not blinking for error.
•
Set the UNCOVER switch to CLOSE (Opposite of
OPEN for DIP switch) position as shown in Figure 25.
•
Press and hold ENTER key as shown in Figure 26.
The STATUS LED for RELAY 1 starts blinking. Blink
the LED according to value of uncover delay.
