Control Transformer (T1)
115V AC control power is obtained via a supplied control power transformer.
The control transformer is fused on the primary.
Bypass Control Interface (CP1)
The operator interface on the bypass option box shows the following LEDs:
• Ready (green) - On when power is applied to the drive-bypass unit.
• Interlock Open (amber) - On when the customer interlock or Aux Fault is
de-energized.
• Bypass Run (green) - On when the bypass contactor (BC) is energized.
• Bypass Trip (red) - On when a bypass fault condition exists (for example,
bypass motor overload has tripped).
• Purge (amber) - On when the purge condition is active.
• Drive Output Enable (Green) - On when the drive output contactor
(DOC) is energized.
In addition, the Bypass Control Interface contains two selector switches. Selector
Switch 1 (SS1) determines the state of the DIC, DOC and BC contactors.
Selector Switch 2 (SS2) determines the source of control logic.
