Operation
Wiring Diagram :
MCY98-54
11 Pin Octal with a DPDT
Contact Configuration.
Pin 9 is Normally Closed
and Pin 11 is Normally
Open.
If the top toggle switch is in “ Alternate” position closing switch S1 will alternate the loads between LA and LB.
If the top toggle switch is in “Lock 1” position load LA is On and load LB is OFF. Switch S1 is not used in the mode.
If the top toggle switch is in “Lock 2” position load LA is OFF and load LB is ON. Switch S1 is not used in the mode.
Note : Input voltage must be applied at all times for proper alternation. The use of a solid state control switch for S1 or S2 may not
initiate alternation correctly. S1 or S2 voltage must be from the same supply as the unit’s input voltage (see wiring diagrams). Loss of
input voltage resets unit; Load a becomes the lead for the next operation.
