HMI Bypass Controller Installation and Commissioning Guide

4.4.2 Starting Operation

There are two (2) basic steps required to begin operation.

Step 1

– Select the operation mode by pressing the VFD or BYP (bypass) icon.

You must select one of these modes. For VFD operation, press the VFD icon.
For bypass operation press the BYP (bypass) icon. Upon selection the selected
icon will be highlighted in green.

Step 2

– Select the start mode by pressing either the HAND or AUTO icon.

Upon selection the selected icon will be highlighted. Selecting HAND allows
an immediate start in VFD or Bypass Mode; whichever was selected in step 1.
RUN will not occur until the customer-supplied run contact closes between
terminals 27 and 1 (AUTO RUN INPUT and 24 Vdc). The RUN status indication
will illuminate when the contact closes.

4.4.3 Ending Operation

Press STOP/(reset) icon once – Cancels the start mode of operation.
