Miller Electric OM-842 Installation, Connecting Remote Pendant Or Equivalent User-Wired Control

SECTION 2 – INSTALLATION

2-1. Connecting Remote Pendant Or Equivalent User-Wired Control

NOTE

A user-wired equivalent to the remote pendant may be connected to the control unit. However, connections must be made for a Stop push button even if it is not used in unit operation. Since the Stop button is wired in a normally closed configuration, if Stop connections are not made, the control unit interprets that as the Stop button being continually pressed. Refer to Figure 8-1 for a circuit diagram of the remote pendant.
