BE SURE TO REMOVE ALL POWER SUPPLYING THIS EQUIPMENT BEFORE CONNECTING OR DISCONNECTING WIRING. READ INSTRUCTIONS BEFORE INSTALLING OR OPERATING THIS DEVICE. KEEP FOR FUTURE REFERENCE.
Installation: Mount the 70170-D 11 pin octal socket in a suitable
enclosure. Wire the socket per the wiring diagram on the side of the time
delay relay. Make sure to match the terminal numbers on the socket to the ones
shown on the wiring diagram (the wiring diagram on the relay is the view
looking towards the bottom of the relay vs. the top of the socket). Use #12-20
solid or stranded copper or copper-clad aluminum wires with 70170D socket and
terminal tightening torque of 12 in-lbs. Plug the time delay relay into the
socket, making sure the key on the center post is in the proper orientation
before insertion. If the relay must be removed from the socket, do NOT rock
the relay back and forth excessively–the center post could be damaged.
NOTE: When the trigger switch is connected to more than one device,
whether it be another Automation Direct time delay relay or another brand,
please review the compatibility of the combination. The potential exists where
different relays have different trigger switch voltages, and combining one
trigger switch on multiple voltages could damage one of the units.
The following step applies only to the TRM-8 Series Multi-Function units (Figure 1):
Setting Function: To set the function, first select one of the eight
TRM-8 Series functions from the Select Function Chart located on the side of
the relay. Position the eight-position rotary switch to the number that
corresponds to the desired function.
NOTE: Function cannot be changed with power applied to the unit.
As a guide, a description of how each function operates is shown on the back
of this sheet.
