Drive Mode
When the IntelliPass is in the Drive mode, the text “E-Energy” is shown on status bar. (If E-Energy function is not active the
text “Ready” will be shown)
When the system is first commanded to run, the output contactor O is energized and the motor is connected to the Drive.
The “O” contactor is controlled by the IntelliPass logic via Relay 2 output. The speed of the motor is determined by the
speed set point of the H-Max Drive. When the H-Max is commanded to stop, the Drive will reduce the speed of the motor
and when the motor speed reaches zero, the output contactor “O” is de-energized and the motor is disconnected from the
IntelliPass. The output contactor also opens immediately if there is a Drive fault. (See Schematic)
The IntelliPass system is also interlocked. When the output contactor ”O” is energized, the Bypass contactor “B” is pre-
vented from being energized by electrical interlocks in each contactor coil control circuit and a logic interlock built in to the
IntelliPass software. (See Schematic)
Bypass Mode
When the IntelliPass is in the Bypass mode, the text “Bypass” is shown on status bar.
When the system is commanded to run in the Bypass mode, the motor is connected to the line through the Bypass contac-
tor (B). The B contactor is controlled by the Drive logic via a Relay 1 output.
The Bypass mode can be selected in 3 ways:
•
Manually via the Drive logic controls (i.e. Keypad, Fieldbus or I/O).
•
Automatically after a Drive fault - if the Auto Bypass feature is active.
•
Manually by a door switch (Option) - Manually using the manual Bypass switch as part of the option M1.
Manual Bypass
Manual Bypass can be activated either by using the Bypass button on the keypad, by using a digital input on the control TB
or from the Fieldbus. The user can toggle between Bypass and Drive modes by pressing the keypad Bypass button or the TB
inputs. Once in the Bypass mode, the start command can be given through any control place (I/O, Keypad, and Fieldbus) in
the same manner as starting in the Drive mode.
