System Check: Motor Connected to ACH550 with E-Clipse Bypass

After performing the control panel checks and setting the ACH550 Drive Start-up
Data parameters, check the operation of the ACH550 Drive with E-Clipse Bypass
with the motor connected as follows:
1. Disconnect and lock out power to the E-Clipse Bypass unit, wait at least five minutes
before disconnecting power.
2. Connect the motor to the output terminals.
CAUTION: If the Bypass Override (Override 2) input contact is closed, the
motor will start across the line as soon as power is applied.
If the Safety Interlock and Run Enable input contacts are closed and the
Smoke Control (Override 1) input contact is closed, the motor will start across
the line as soon as power is applied.
If the Start/Stop, Safety Interlock and Run Enable input contacts are closed
and the system is in the Bypass mode and in either Hand or Auto, the motor
will start across the line as soon as power is applied.
If the Start/Stop, Safety Interlock and Run Enable input contacts are closed
and the system is in the Drive mode with the drive in either Hand or Auto
mode, the motor will start on the drive as soon as power is applied.
In order to prevent the motor from starting, the system should be in the Drive
mode and the drive should be OFF when the power is disconnected at the end
of the previous series of control panel settings and checks.
In order to prevent the motor from running without disconnecting the motor,
open the Run Enable and Safety Interlock contacts on bypass control board
terminals X2:2, X2:3 and X2:4 before applying power. Set the bypass to Drive
mode and the drive to OFF.
3. Apply power to the E-Clipse Bypass unit. The ACH550 Control Panel display should
be illuminated. On the bypass control panel, both the display and Enabled LED
should be illuminated. If the Enabled LED is not illuminated solid green, check to see
