I. BASIC OPERATION
This relay required 115 volts 50/60Hz control power connected to terminals 2 and 10.
To connect the proximity sensor connect the brown (+) positive wire to terminal 6 and
the blue (-) negative wire to terminal 7.
Modes Of Operation:
DIP-SWITCH #1 ON; The relay operates and the time period starts when control
power is applied. If an input pulse is received before the end of the set time period, the
relay continues operating for a full new time period starting at the leading edge of the
input pulse. If the set time period expires before a new input pulse is received, the
relay releases.
DIP-SWITCH #1 OFF; The relay operates and the time period starts at the leading
edge of the first input pulse. If a new input pulse is received before the end of the set
time period, the relay continues operating for a full new time period starting at the
leading edge of the new input pulse. If the set time expires before a new input pulse is
received, the relay releases.
