There are 16 more LED lights are provided to indicate the position of the speed cams, limit cams
and modes of operation. When a cam blocks an optical sensor, the function is activated and the
corresponding LED light turns on (see Figure 7.2.B.2). The 16 LED lights are:
1. HSC: High Speed Close.
2. FSC: Final Speed Close.
3. DCL: Door Close Limit (DCL output relay is energized when the DCL LED light turns on).
4. SSO: Slow Start Open.
5. HSO: High Speed Open.
6. MSO: Medium Speed Open.
7. FSO: Final Speed Open.
Note: The combination of Cam#1(SSO/FSO) and Cam#2(MSO) produces
SSO, HSO, MSO, and FSO. See 7.7 CAM SETTINGS VS. DISTANCE for
appropriate settings.
8. DOL: Door Open Limit (DOL output relay is energized when the DOL LED light turns on).
9. HOLDING: Door is in its full open or full close position. (When the door is fully open or fully
closed, a minimal amount of power is applied to the motor to prevent drifting).
10. NUDG. Door is closing at reduced speed (nudging).
11. RE-OPEN: Door re-opening features have activated. (RE-OPEN output relay is energized
when the RE-OPEN LED light turns on).
12. STALL REVERSE: In the close direction, if the door exceeds the Torque Limit set by Par. 9,
the STALL REVERSE LED will turn on and the RE-OPEN relay will be energized).
13. FREQ. FAILURE: In the close direction, if the door exceeds the Speed Limit set by Par. 0, the
FREQ. FAILURE LED will turn on and the RE-OPEN relay will be energized).
14. DPM: A car door closed contact for safety features such as G.A.L. Fault monitor. (DPM relay is
energized when the DPM LED light turns on).
15. FAULT: The FAULT LED on indicates that there is a Fault in the drive.
16. AUX.: The AUX. LED and the AUX. relay will turn on when AUX cam is activated. AUX. cam
and AUX. cam are optional and available upon request.
