Test Switches for Proper Operation

NOTE: To ensure the safety and the integrity of the machine, it is recommended that one person should

test the limit switches while another person is available to disconnect the power supply in the

event of limit switch failure.

Step 1: Operate the machine in the close mode (drive block will be traveling towards the motor). While

the machine is closing, pull down on the adjustment rod (towards the motor) to activate the limit

switch and the motor should stop*.

Step 2: Operate the machine in the open mode (drive block will be traveling away from the motor). While

the machine is opening, push up on the adjustment rod (away from the motor) to activate the limit

switch and the motor should stop*.

* If the machine does not stop, disconnect and lock out power to the machine immediately.

After power is disconnected, check the wiring and connections and repeat Step 1 and Step 2.
