4. Setup and Installation
Follow these steps for proper installation of the Harmony XB4BW33G5 push button:
- Power Disconnection: Ensure all power to the control panel or machine is disconnected and locked out before beginning installation.
- Panel Cutout: Create a standard 22mm diameter cutout in the control panel. Ensure the panel thickness is within the specified range for the device's mounting bracket.
- Mounting the Head: Insert the push button head (actuator) through the front of the panel cutout.
- Securing the Bezel: From the rear of the panel, place the mounting bracket and tighten the securing nut or ring to firmly hold the push button head in place. Do not overtighten.
- Attaching Contact Blocks: Attach the contact blocks (1 NO and 1 NC) and the integrated LED unit to the rear of the push button assembly. Ensure they are securely clicked into place.
- Wiring: Connect the control circuit wires to the screw terminals on the contact blocks.
- Connect the power supply (110-120V AC/DC) to the integrated LED terminals (typically marked X1 and X2).
- Connect the Normally Open (NO) contacts to the circuit that should close when the button is pressed.
- Connect the Normally Closed (NC) contacts to the circuit that should open when the button is pressed.
- Ensure all connections are tight and secure.
- Verification: Double-check all connections and ensure no loose wires are present.
- Power Restoration: Restore power and test the functionality of the push button.
