LED STATUS
24VDC: Accommodates accessory power up to
1
/2 A. CAUTION: Accessories other than 24 Vdc or rated higher
than
1
/2 A require a separate power supply (not provided–See NOTE at Status LED below).
AUX2: Activates devices such as another unit in a 2-stage
security application.
ALARM: Activates devices such as lights or alarms when
gate is obstructed.
LOCK2: Provides a contact closure when the gate is in
motion.
LOCK1: Provides a contact closure when the gate is not
in motion.
Battery Terminals
The battery terminals provide the GTO/PRO SL-5100 and GTO/PRO SL-6100 gate operators with back-up power in
the event of an AC power failure. Two 12 V GTO back-up batteries are shipped installed and wired to the control board.
No adjustments or other connections to the batteries or terminals are necessary.
The GTO back-up batteries should be replaced every five (5) years to prevent interruptions in gate operator function.
USE ONLY GTO APPROVED BACK-UP BATTERIES. Call the GTO Service Department at [phone] for
more information.
Inverter
A 390 V inverter (bolted to the inner plate of the control box above the control board) controls the battery back-up
feature of the GTO/PRO SL-5100 and GTO/PRO SL-6100 gate operators. The inverter will retain voltage for a
minimum of 5 minutes after operator power is shut down.
The inverter is protected by a non-removable safety cover and a tamper-evident seal. There are no serviceable parts
in the inverter– if the inverter fails to function properly, call the GTO Service Department at [phone].
DO NOT ATTEMPT TO REMOVE THE SAFETY COVER FROM THE INVERTER! THE HIGH
VOLTAGE OF THE INVERTER CAN CAUSE SERIOUS INJURY OR DEATH!
THE WARRANTY OF THE GATE OPERATOR IS VOID IF THE SAFETY COVER OR TAMPER-
EVIDENT SEAL IS REMOVED FROM THE INVERTER.
Status LED
The green STATUS LED should be on when power is being
delivered to the system. If the STATUS LED is not on or goes out,
the current draw for the 24VDC terminal may be excessive. Only
accessories rated for
1
/2 A or less can be connected to the 24VDC
terminal (see note at 24VDC above).
