Setup Step Database
In the step database, all settings and data are combined which are required to adjust and adapt
the steps.

Discharge time
0,5...1200
s
The discharge time is defined once and is valid for all steps. The
discharge time is a lockout time, which expires after switching off a
step. Until this time has not expired, the corresponding step for the
regulation is not available. The discharge time should be adapted to
the discharge unit of the capacitor.
402
Capacitor size
Ct*Pt*7000
If the automatic size-detection is disabled, then it is necessary to
enter the nominal step size. The input is done in var and is related to
nominal voltage. The adjustment must be done separately for each
output.
Warning:
Before the step size is set, must be set the correct current
and voltage transformer ratio since the max. possible steps size is
limited by these ratios. After an step size has been entered, should
the current and voltage transformers ratio will not changed because
these changes affect the set step size. Hand-programmed "normal"
steps will be overwritten by the automatic step size detection

Type of output
Auto/Al/FOn/FOff
For each step the function can be set separately. The following
functions can be selected:
Auto = Step is used in the normal control algorithm
Alarm = If the set temperature limit 1 is exceeded this step is
switched as fan output.
Fon = Step is permanently switched on (Step is still
monitored and shut down in critical situations)
Foff = Step is permanently switched off
flty = Step was switched three times without success and is
not longer used for the control. Defective steps flashing in
the step indication.
If defective steps should not be locked, you must disable this
function under the menu item "309".
Steps which are identified as defective will be tested again by the
controller every 24 hours or after a restart.
