LED LED NAME DESCRIPTION
RELAY DRIVE TROUBLESHOOTING LEDS
There are 5 troubleshooting LEDs on relay drives K1 through K5. These LEDs will be illuminated when the microcontroller relay drive is
activated.
D6 Contactor A On when Contactor A is activated
D5 Contactor B On when Contactor B is activated
D4 SAM On when SAM relay is activated
D3 Lock On when Mag Lock relay is activated
D2 Alarm On when Alarm Relay is activated
TROUBLESHOOTING LEDS
There are 9 troubleshooting LEDs.
D11 Radio On when Radio switch is activated
D13 Shadow On when Shadow Loop is activated
D15 Hard Close On when Close switch is activated
D17 (Green) Stop On when Stop switch is not activated
D19 Soft Open On when Open switch is activated
D21 Hard Open On when Open switch is activated
D24 Interrupt (Safety) Loop On when Interrupt/Safety Loop activated
D29 Obstruction Open On when Edge is activated or when Photo Eye
Beam is broken
D31 Obstruction Close On when Edge is activated or when Photo Eye
Beam is broken
FORCE CONTROL
Set the force control pot such that the unit will complete a full
cycle of gate travel but can be reversed off an obstruction without
applying an unreasonable amount of force. On most operators
this will be around the middle of the range.
NOTE: For LED location refer to illustration on previous page.
DIAGNOSTICS (LEDS AND CODES)
There are three diagnostic LEDs. Two red LEDs (OLS, CLS) are
indicators for the open and close limits. The LEDs are illuminated
when the limit switch contacts are closed.
The third amber LED (DIAG) is used to blink out diagnostic
codes. The number is the count of the number of times the LED
is on in an 8 second period. The LED is on for approximately 1/2
second and repeats every second until the number is reached.
There will be a pause following each pulse cycle (1-6 pulses) to
differentiate between the different diagnostic codes.
