ACH580 Installation, Operation and Maintenance Manual
Note: If the ACH580 Control Panel displays an Overcurrent, Short circuit or Earth
leakage fault, disconnect and lock out power to the E-Clipse Bypass unit. Wait at
least 5 minutes. Disconnect the motor leads from the E-Clipse Bypass unit and
Megger each motor lead to ground to determine if the motor is good. Check the
power leads from the Drive / Bypass to the motor for damaged or improper wiring. If
the ACH580 Control Panel displays any other drive faults, correct the fault condition
before proceeding to the next step.
CAUTION: Check motor rotation direction as soon as the motor begins to move. If
motor does not rotate in the correct direction, shut down the drive, disconnect and
lock out power to the drive and wait five minutes. Swap any two motor output wires
(T1, T2, and T3). Incorrect motor rotation direction may cause equipment damage.
7. Increase the speed to 60 Hz or the highest safe operating speed.
8. Press the OFF key on the drive control panel. The motor should stop.
If the drive does not operate according to these steps, refer to the ACH580 HVAC
control program firmware manual.
If the drive operates according to these steps, your ACH580 with E-Clipse Bypass is
ready to use with preset or modified macro settings.
Note: The settings for ALL external serial communication between the ACH580 with
E-Clipse Bypass and any Building Automation System are configured using the
E-Clipse Bypass operator panel. DO NOT attempt to configure the external serial
communication connection using the ACH580 operator panel!
The settings for internal communication between the ACH580 and the E-Clipse
Bypass are configured at the factory and require no adjustment.
Note: On the ACH580 drive, Parameter 9521, bit 5 must be set for proper operation
with the E Clipse Bypass. When this bit is set, the following ACH580 parameter
values are set and write protected:
20.01 – Ext1 commands
