Pre-Transfer
➀ Use Cutler-Hammer cable CAT#IMPCABLE, STYLE #2A95705G01 or BELDEN 9463
cable family.
➁ Use a 100 ohm 1/2 watt terminating resistor on the most remote device.
➂ Where devices are daisy chained, tie the shielding together for continuity. Tie the shield to
connector J4 terminal 17 of the IQ Transfer. On the last device in the network tie the shield
back and tape.
➃ Use Cutler-Hammer Addressable Relay II — CAT #ARII, STYLE # 5302C07G02.

4.4.2 LOAD SEQUENCING SUB-NETWORK
The Load Sequencing signal allows loads to be activated in a sequence after a transfer has taken place.
Addressable Relay II’s are used to enable up to 10 separate loads.
The Addressable Relay II must be set for:
• 1200 BAUD rate
• WATCHDOG feature disabled
• RELAY PULSE feature disabled
• Address range from 002 to 00B
Immediately before the transfer switch has moved from
the neutral position to the new source, all 10 of the
sequence relays are sent open commands. The IQ
Transfer will make several attempts to communicate
with a relay. If an address or relay is not used or if a
relay fails to respond, the IQ Transfer will move on to
the next relay. Once the attempt to turn all the relays off
has been made, the IQ Transfer will start to sequence
the 10 relays on. Starting with address 002, the IQ
Transfer will send the relay the command to close. After
this relay responds, the IQ Transfer will start the Time
Delay Sequence timer (TSEQ). When this timer has
counted down to zero, the IQ Transfer will increment to
the next address of 003 and send it the close command.
Should there be no relay, the IQ Transfer will display the
NO R xx (where xx is the address) message on the front
panel, abort the time delay and then step to the next
address. This will continue until a relay that responds is
reached or after address 00B, which is the last address,
is tested.
