ACH580 E-Clipse bypass and packaged drive user manual
Communications Control (16) [COMM CTRL]
If configured for Communications Control, the relay is energized when the
appropriate ON command is provided over the communications connection. The
relay is de-energized when the appropriate OFF command is provided over the
communications connection.
System Warning (17) [SYS WARNING]
If configured for System Warning, the relay is energized when a drive/bypass
warning is present. The specific nature of the warning is indicated on either the drive
control panel display or the bypass control panel display, depending upon the
origination of the warning. The System Warning relay is de-energized during normal
operation.
Bypass Fault/Warning (18) [BYP FLT/WRN]
If configured for Bypass Fault/Warning , the relay is energized when either a bypass
fault has occurred, the bypass motor overload/underload protection has tripped or
when a bypass warning condition is present. The Bypass Fault/Warning relay is
de-energized during normal operation.
Bypass Overload (19) [BYP OVERLD]
If configured for Bypass Overload, the relay is energized when the bypass motor
overload level has exceeded the programmed protection setting. The Bypass
Overload relay is de-energized during normal operation.
Bypass Underload (20) [BYP UNDERLD]
If configured for Bypass Underload, the relay is energized when the bypass motor
underload level has fallen below the programmed protection setting. This output is
often used for broken belt indication. The Bypass Underload relay is de-energized
during normal operation.
PCB Overtemperature (21) [PCB OVERTMP]
If configured for PCB Overtemperature, the relay is energized when the temperature
of the bypass control, printed circuit board has exceeded the fixed protection setting.
The PCB Overtemperature relay is de-energized during normal operation.
System Underload (22) [SYS UNDERLD]
If configured for System Underload, the relay is energized when either the drive or
bypass motor underload level has fallen below the programmed protection setting.
This output is often used for broken belt indication. The System Underload relay is
de-energized during normal operation.
System Fault (23) [SYSTEM FLT]
If configured for System Fault, the relay is energized when either a drive/bypass fault
has occurred or the bypass motor overload/underload protection has tripped. The
System Fault relay is de-energized during normal operation.
System Fault/Warning (24) [SYS FLT/WRN]
If configured for System Fault/Warning, the relay is energized when either a drive/
bypass fault has occurred, the bypass motor overload/underload protection has
