3.1 Control Panel Component Checks
This section will cover the initial system checkout to be done prior to configuring and commissioning the
system through the HMI menu system.
It is necessary to confirm that all of the integral components and interconnecting wiring are in place and
secure. Vibration and jarring from transport or installation may have loosened components or wiring terminals.
It is good practice to check all system components for integrity and tightness prior to initial power-up of the
system. Any external interlock and remote signal wiring should also be connected to the boiler controller.
3.1.1 DIN Rail Latch and Expansion I/O Module Locking Levers
Before powering up the control system for the first time, check that all the DIN rail latches and expansion
module locking levers are in place (see Figure 3-1 and Figure 3-2).
The module locking levers should all be securely seated to the left.
The base unit and expansion modules do not support removal and insertion under power. While the PLC
system is under power, any break in the connection between the power supply and the base unit (i.e.
removing the power supply, base unit, or an expansion module) will clear processor memory including the
user program. Ensure that the electrical power is OFF before removing or inserting any PLC device.
