Operating manual V2.0
To start a trip the HSE switches on first the "Enable" signal of the VVVF. Then the lift
controller waits for the "Ready" signal of the inverter. If this feedback signal is not set within
the specified time (parameter "Ready=1"; default 1s), then the HSE disables the signal again
and generates an error message. Within this second, it is hardly possible to measure if the
"Enable" signal reaches the VVVF correctly or whether the VVVF activates the "Ready"
signal , but is connected incorrectly to the HSE .
By setting the parameter "Ready=1" now to a value of 30 seconds, there is enough time to
measure the signals with a multimeter.
Another way to diagnose theses error is to set individual signals by the menu "Hardware test"
or, for example, to switch on contactors manually and to control the feedback signals.

4.13 Fault output

Any one or more outputs of the HSE, FVE, TSE or ESE can be configured as fault message
output.
When an error has occurred then, after a time delay (parameter " Err.delay[s]"), these
outputs are enabled.
