Trips and Diagnostic
Procedures
System trips with values in the range of #40 – 50, and
trip 100 are E-Flo Plus specific.
Trips #40 – 50 will cause the system to shutdown upon
becoming active. Trip 100 is reserved for a system alarm
reset.
An external trip is also configured specifically for E-Flo
Plus; its trip code is Et. This trip becomes active if one of
the following conditions is true:
•
Power is applied to the motor while Secure Disable
circuit is disconnected (normally closed switch is
open). It is therefore recommended to connect
Secure Disable circuit (normally closed switch is
closed) before applying power to the motor.
•
VFD/Apps module(s) reset is initiated while Secure
Disable circuit is disconnected (normally closed
switch is open). It is therefore recommended to con-
nect Secure Disable circuit (normally closed switch
is closed) before performing system reset,
The CL2 trip becomes active if the pressure sensor sig-
nal is lost.
