G. LED indicators:
There are 7 LEDs on the Parameter Unit. DO, DC, NUD, HLD, PRG, FLT, OVT.
DO=Door Open, DC=Door Close, NUD=Nudging, HLD=Holding, PRG=Programming Mode,
FLT=Fault, OVT=Over Torque. These LEDs indicate the present status of the MOVFR.
7.6 Parameter adjustments:
CAUTION! All equipment must be installed and adjusted to meet Federal, State, and Local Codes.
NOTE 1: The closing Kinetic Energy is affected by the speed and the mass of the
door. The closing Kinetic Energy must not exceed Code Limits.
For more details about the Kinetic Energy of the G.A.L door operators,
go to http://www.gal.com
NOTE 2: The closing Torque is affected by the Torque adjustment.
The closing Torque must not exceed Code Limits.
NOTE 3: Whenever changing any value in the Closing Direction Parameters, the
door should be rechecked to meet the Code requirement.
A. Closing sequence:
MAXIMUM CLOSE SPEED (Par. 0):
This Parameter is the Limit of the Closing speed. The Default value of this Parameter is 30Hz.
If the Closing speed is higher than 30Hz, the Drive will turn on the Frequency Failure (FF) output
and activate the Reopen Relay. Users should bear in mind that the Reopen Relay Contact, once
activated, will send the re-open signal to the Main Controller ONLY and will wait for the OPEN signal
from the Main Controller to Reopen the door. The Reopen Relay will NOT reopen the door by itself.
HOLDING TORQUE (Par. 1):
The Holding Torque is activated when the door reaches DOL or DCL.
HOLDING SPEED (Par. 2):
The Holding Speed is activated when the door reaches DOL or DCL.
NOTE: The reason to apply the Holding Power when the door is fully closed or fully
open is to prevent the door from drifting or rolling back.
CAUTION! The Holding power should be less than 15W to prevent the motor
from unnecessary heating, which would reduce its life.
HIGH SPEED CLOSE – HSC (Par. 4):
This is the highest speed for the overall Closing sequence. A higher value produces the faster speed.
FINAL SPEED CLOSE – FSC (Par. 5):
This is the Final Closing Speed. It should be set reasonably low so that when the DCL (Door Close
Limit) and the Close Stop Roller are reached without slamming or bouncing.
