8 Error messages and alarms
UCEsat 1 protec-
tive switch-off Error in the power output stage. To prevent
destruction of the device, a firing pulse in-
hibit is triggered permanently. The device must be returned to JUMO
for repair.
UCEsat 2 protec-
tive switch-off
Fault current too
high The error current monitoring using external
current sensors has detected that the error
current limit value has been exceeded. Rectify the cause of the error cur-
rent.
Failure fan 1, 2 Fan 1/2 does not reach the necessary
speed. Check fan for freedom of movement
(dirt).
[xxx] Invalid
configuration The value range of a configured parameter
has not been complied with. A firing pulse
inhibit has therefore been triggered for
some parameters.
