OPERATION RESET BUTTON The reset button is located on the side of the control box and serves several functions: • Press the reset button to stop a moving gate/door during a normal open/close cycle, like a stop button. • Press the reset button once while the gate/door is in open position to disable the Timer-to-Close. The gate/door will stay in the open position. To restart the Timer-to-Close either press the reset button or activate the gate/door with a programmed remote control. • Press the reset button to shut off the alarm and reset the operator. OPERATOR ALARM A If a contact sensor detects an obstruction twice consecutively the alarm will sound (up to 5 minutes) and the operator will need to be reset. If a command is given after the initial 5 minutes the operator will beep. The operator alarm will beep 3 times with a command if the battery is low. When the inherent force of the operator (RPM/current sensor) detects the following (twice consecutively) the alarm will sound (up to 5 minutes) and the operator will need to be reset: A. The gate/door hits an obstruction. B. The gate/door has a broken wheel(s) or damaged track. C C. The gate/door has broken springs or hardware. D. Trolley is hitting the chassis or an unwanted object. Remove any obstructions. Toggle the reset switch to shut off the alarm and reset the operator. After the operator is reset, normal functions will resume. ADJUSTABLE OPEN SPEED The HCTDCU provides a high speed open option to help flow in high traffic areas. Select the open speed using the BIPART DELAY switch. BIPART DELAY OFF (default) = 8 in./sec. open speed BIPART DELAY ON (fast) = 11 in./sec. open speed NOTE: After changing the open speed, the force will need to be reset to account for the change of power used, see page 17. REMOTE CONTROL SINGLE BUTTON CONTROL (SBC) FUNCTIONALITY Once the remote control has been programmed the operator will operate as follows: When gate/door is in the closed position, activation of the remote control button will open the gate/door. During the open cycle another activation of the remote control will stop the gate/door and the next activation of the remote control will close the gate/door. When the gate/door is in the open position, activation of the remote control button will close the gate/door. If the remote control is activated while the gate/door is closing, the gate/door will stop and the next activation will open the gate/door. 25 Reset Button B D
