Timer programming:

Sequential Timer Programming:

Fix switch RUN/PROG in position PROG
For sequential timer selection fix switch SEQ/COMB in position SEQ. Supply power to inputs A1 and A2
Using the button RELAY select the channel 1
Using the button DLY/ON select time DLY for time setting, during which the contacts of channel relay will be open
Press RANGE for selection of necessary time range
Using arrow button to set the necessary time
Repeat steps 4 through 6 for status time setting ON, during which the contacts of channel relay will be closed
Repeat steps 3 through 7 for setting of other channels

Combination Timer Programming:

Fix switch RUN/PROG in position PROG
For selection of combination timer fix switch SEQ/COMB in position COMB. Energize the inputs A1 and A2
Using button RELAY select channel 1
Using button COMBINATION select combination 1
Using button DLY/ON select time DLY for time setting, during which the contacts of channel relay will be open
Press RANGE for selection of necessary time range
Using arrow buttons set the necessary time
Repeat steps 5 through 7 for set of status ON, during which contacts of channel relay will be closed
Repeat steps 4 through 8 for setting the other channel combinations
Repeat steps 3 through 9 for setting of other channels and their combinations
