Auxiliary Relays - Chamberlain LA500DC Installation Manual

AUXILIARY RELAYS

AUX RELAY 1 AND 2
Normally Open (N.O.) and Normally Closed (N.C.) relay contacts to control external devices, for connection of Class 2, low voltage (42 Vdc [34 Vac] max
5 Amps) power sources only. Function of relay contact activation determined by switch settings.

CYCLE COUNT
* First, note the current Aux Relay switch positions. To determine the
actual cycles that the gate operator has run (in thousands), set all three
Aux Relay switches to the ON setting for Aux Relay 1. The Expansion
Board's 1, 2, and 3 LEDs will blink out the cycle count, with 1 LED
blinking 1000's, 2 LED blinking 10,000's, 3 LED blinking 100,000's, and
simultaneously all three LED's blink 1,000,000's (e.g. 1 LED blinks 3
times, 2 LED blinks 6 times, and 3 LED blinks once. Cycle count is
163,000.). Cycle count displayed is between 1,000 and 9,999,000
cycles. After servicing, set Aux Relay switches back to their appropriate
positions. Cycle count cannot be reset or changed. If under 1,000
cycles the 1, 2, and 3 LEDs will turn on for 10 seconds, then turn off.
NOTE: The expansion board will flash the cycle count 3 times then all the
LEDs will turn on solid for 10 seconds then turn off.

Relay always off. Use this Aux Relay setting to conserve battery power.
Energizes at open limit. Use with SAMS (Sequenced Access Management System, jointly with barrier gate).
Energizes when not at close limit. For an additional audible or visual display, connect an external light (low voltage).
Energizes when motor is on (gate in motion). For an additional audible or visual display, connect an external buzzer or light (low voltage).
Energizes 3 seconds before gate motion and remains energized during
gate motion. The onboard alarm will sound. For an additional audible
or visual display, connect an external buzzer or light (low voltage).
Energizes when AC power or solar power is present. There is
approximately a 10-12 second delay before relay cutoff, after AC
shutdown.
Energizes if gate is manually tampered with by being pushed off of
close limit. For an additional audible or visual display, connect an
external buzzer or light (low voltage).
The 1, 2, and 3 LEDs will blink out the cycle count (cycle count is
stored on the control board). See below.

Energizes 3 seconds before gate motion and remains
energized during gate motion. For an additional audible or
visual display, connect an external buzzer or light (low voltage).
Energizes when on battery power. There is approximately
a 10-12 second delay before relay cutoff, after AC
shutdown.
Energizes if gate is manually tampered with by being pushed
off of close limit. For an additional audible or visual display,
connect an external buzzer or light (low voltage).
