How To Learn Or Erase The Remote; How To Use The Remote To Control The Operator; Troubleshooting - LockMaster SFG 18H User Manual

Put an immobile object along the gate path, and then operate the gate to strike it during the open and close
cycles. The gate must reverse as soon as object is struck with it. If the gate doesn't reverse, please increase
the reversing sensitivity by turning the potentiometer in counter-clockwise direction. (Turning the stall force
potentiometer toward to MIN position to increase the reversing sensitivity)
Note 1: If the sensitivity setting is too higher, the gate will stop or reverses very easy by itself while
there is little obstruction or resistance such as strong wind or heavy snow sometimes.
Note 2: Always check the gate reversing function every each time of control board set or restart after
power off.

How to learn or erase the remote

Learn the remote
Press and release the learn button, the REM LED
light will be on, then press the key in the
remote twice in 2 seconds, the REM LED
light will flash for 4 seconds. Now the
remote has been learnt successfully.
Erase all the remote codes
Press and hold the learn button until the REM LED light is off. Now all remote codes have been erased.

How to use the remote to control the operator

Key A is used to operate the operator to work alternately (open-stop-close-
stop-open).
When the Midway Mode function is enabled, Key B is used to achieve the
Midway Mode function (open the gate for the pre-setting time). When the
Midway Mode function is disabled, the operator works alternately (open-stop
-close-stop-open) by pressing Key B.

Troubleshooting

Have a multimeter to check voltage and continuity. Use caution when checking high voltage terminals.
1. Motor only runs toward one direction.
a. The limit switch is failed. Disconnect the limit switches and try it again.
b. The start capacitor of the motor is failed. Replace the capacitor.
c. The electric component on the control board may be damaged. Replace the electric component or replace
the control board.
2. The gate does not open or close.
a. The power switch is OFF. Make sure the power switch is ON.
b. The limit switches are failed. Disconnect the limit switches and try it again.
c. Connecting wires or terminal blocks are too loose. Check the connecting wires and terminal blocks.
d. The motor has been damaged. Replace the motor if necessary.
e. The thermal protector is working because the high temperature after long working time. Please wait for 20
minutes to let the motor become cold.
