22 E-Clipse Bypass Configurations for ACH550 Drives
Installation
Note! The settings for ALL external serial communication between the ACH550 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 ACH550 operator panel!
The settings for internal communication between the ACH550 and the E-Clipse
Bypass are configured at the factory and require no adjustment.
Note! Both the ACH550 Drive and the E-Clipse Bypass include preset application
macros. The only ACH550 Drive macro that provides the proper configuration
settings by default is the "E-Clipse" macro (9902 = 15). If any other ACH550 drive
macro or any modified setting of the "E-Clipse" macro is used the following ACH550
Drive parameter values must be set and power cycled or the E-Clipse Bypass will
not function properly:
• Parameter 9802 must be set to “STD MODBUS”
• Parameter 1001 must be set to “Comm”
• Parameter 1002 must be set to “Comm”
• Parameter 1601 must be set to “Comm”
• Parameter 1608 must be set to “Comm”
• Parameter 5303 must be set to “76.8 kb/s”
• Parameter 5304 must be set to “8 EVEN 1”
• Parameter 5305 must be set to “DCU PROFILE”
• Parameter 5310 must be set to “103”
• Parameter 5311 must be set to “104”
• Power must be cycled
Refer to the ACH550-UH User’s Manual for programming instructions.
Note! Run motor from drive before attempting bypass operation.
System Check: Motor Disconnected from the ACH550 with E-Clipse Bypass
If you are familiar with the E-Clipse Bypass operation, you may skip the following
section. Otherwise, after performing the system checks and setting the ACH550
Drive Start-up Data parameters, become familiar with the operation of the ACH550
Drive with E-Clipse Bypass without the motor connected as follows:
1. Disconnect and lock out power to the E-Clipse Bypass unit, wait at least five minutes
after disconnecting power.
2. Disconnect the motor from the E-Clipse Bypass unit.
3. Apply power to the E-Clipse Bypass unit by turning on the branch circuit disconnect
device and the bypass disconnect switch or circuit breaker.
