CONTROLS
KEYPAD The 12-key keypad is used for local operation, programming and service.
SWITCH S1
GATE OPEN TO Selects the direction the gate will open for typical installation (left) and
LEFT/RIGHT restricted installation (Right).
SWITCH S2
POWER FAIL Selects the direction the Power Fail Operation option will move the gate
(LEFT/RIGHT) (Left/Right) if AC power fails.
INDICATORS
LED indicators light when controls and inputs are active. Additional indicators are as follows:
DISPLAY This is a seven segment character display that gives numerical response to
service personnel during programming and operation.
LEFT LIMIT Indicates that the LEFT limit switch is activated.
RIGHT LIMIT Indicates that the RIGHT limit switch is activated.
MTR LEFT Indicates that the gate is moving counterclockwise.
MTR RIGHT Indicates that the gate is moving clockwise.
XMIT Indicates data is being sent to the other unit in a Master/Slave system.
RECV Indicates data is being received from the other unit in a Master/Slave system.
LINE Indicates the ring detect for an incoming telephone call and if the phone line is
available when the gate operator wants to initiate a call.
OFF HOOK Indicates the gate operator is off hook and using the phone line.
FAULT Indicates a fault in the system. See Fault List in Part 5, Troubleshooting and
Maintenance.
MAX RUN TIME Indicates the motor ran for more than 75 seconds without reaching a limit switch,
and was stopped. Usually requires mechanical service. See Fault List in Part 5,
Troubleshooting and Maintenance.
REVERSE Indicates the peak motor current threshold was reached. See Fault List in Part 5,
Troubleshooting and Maintenance.
OVERLOAD Indicates that the average motor current threshold was reached. See Fault List
in Part 5, Troubleshooting and Maintenance.
OPEN MTR Indicates the motor is engaged, but is not drawing any current. The thermal
overload switch on the motor may need to be reset. See Fault List in Part 5,
Troubleshooting and Maintenance.
FUNCTIONAL INPUTS
NOTES: ! The term “activation” means closing an input circuit (via a relay or switch), and may be
momentary or continuous. Momentary activations are superseded by any command.
Continuous activations are superseded only by an overriding command.
" Activating any command when gate is at the open limit stops the Reclose Timer. When
any command (except Manual Close and Stop) clears, the Reclose Timer is reset.
MANUAL INPUTS: OPEN, CLOSE, AND STOP (TB2)
MAN OPEN Activation fully opens the gate. Continuous activation holds gate open.
Man Open overrides Anti-Tailgate (ATG, Reclose Timer, and all controls but
Man Stop.
