BASIC PROGRAMMING
DETERMINE THE WIRING TYPE
The functionality of this operator is based on the wiring type. The
operator is shipped from the factory in standard C2 wiring type
(factory default). Some wiring types will require an optional safety
device. Refer to the following descriptions of wiring types,
requirements and programming.
NOTE: 1. The LED on the logic board will blink once when in C2
and twice when in B2.
2. The operator will automatically convert to B2 wiring (option
D) when Monitored Safety Device is installed. If the
Monitored Safety Device is removed, the operator will go
into a Restricted Close mode**. Turn power OFF and ON to
reset wiring type.
** Restricted close mode requires a constant pressure close
command. The operator will begin closing after a 5 second delay
and will continue to close to the close limit switch. The operator
will stop if the pressure to close is released before reaching the
close limit.
C2 WIRING TYPE WITHOUT MONITORED SAFETY DEVICE
A
(Factory Default)
• Momentary contact to open and stop with constant
pressure to close.
• Open override that reverses when closing by any opening
device.
• Wiring for safety device to reverse. NOTE: The operator
will automatically convert to B2 wiring (option D) when
Monitored Safety Device is installed. (See accessories
page for Monitored Safety Devices)
Start with operator in factory default C2 mode.
Press and hold the LEARN and CLOSE buttons until the LED goes
out (approximately 3 seconds).
