* OLP=On line programming
HOLD: When the slide switch on the front panel is kept in the hold position, the Timing data is
retained in case of power failure. Upon resumption of power the timing continues from the point
where it has stopped.
RESTART: When the slide switch is kept in the restart position, the timer resets in case of power
failure and starts from beginning upon power resumption.
EXTERNAL START: By shorting terminals S1 and S2 for minimum period of 120
milliseconds (potential free shorting) or by keeping S1 and S2 permanently shorted, the timer
sequence is initiated.
SINGLE CYCLE OPERATION: By keeping the terminals C1 and C2 shorted (potential
Free) on the front panel, the sequential switching of output is executed for one Cycle and stops.
CYCLIC OPERATION: By keeping the terminals C1 and C2 on the front panel open, the
Sequential switching of outputs keeps repeating after the end of each cycle.
INHIBIT: By shorting terminals I1 and I2 (potential free) on the front panel, status of relays/triac
output (ON or OFF) is maintained irrespective of the program timing. By removing the short, the
programmed timing continues and relay / triac respond as per the preprogrammed timings.
