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