Eaton H-Max Series - M1 - Manual Bypass Switch

M1 - Manual Bypass (forced) Switch
This option is available on the IntelliPass models only. This option includes an input contactor “I”, L4 pilot light option and a 3
position door mounted selector switch - marked Drives/Off/Bypass. This switch manually overrides the Bypass control from
the system (keypad) and puts unit in bypass or in an OFF mode. See IntelliPass Schematic with M1 option.
When the door switch is in the Drive position, the H-Max Drive logic controls the motor and the keypad selects the operation
(Drive or Bypass), the control source and place (HOA, KEYPAD or Terminal block). The input contactor “I” is energized at all
times while in the drive mode.
When the door switch is moved to Bypass, three actions occur: 1) Drive input isolation contactor is forced open, 2) Drive
output contactor will be forced open and the bypass contactor will be forced closed. The motor will immediately start and run
full speed across the line regardless of the state of the system or drive.3) The Drive will be forced to the bypass mode and
the Keypad Display will show “Bypass”. When the switch is moved back the Drive position, Drive operation is restored and
the system may need to be restarted.
When the switch is in the off position neither the drive or bypass operation is possible. Moving the Switch to the off or
bypass position while the Drive is operating may cause the Drive to fault because the input power to the drive is removed by
the input contactor. See L4 for description/operation of the door mounted pilot lights.
