Electronically Controlled Bypass (ECB) Oper-
ation
Operation
ECB detected faults are reported by the drive in three ways: warnings and alarms are displayed on the keypad
display, through serial communication, or through output relays. The drive provides a form-C fault relay on
terminals 01, 02, and 03. The fault contacts are fail-safe, meaning that if power is removed the contacts close
and a fault condition is reported.
The drive monitors the ECB card communication and detects when communication stops. An ECB card failure
or communication error could cause this. Contact Traneusing the phone number on the back of this manual for
technical support if this happens.
