on page 31) (default setting: hold mode off).
8.7.14 Restart delay after Reset
This element is first available as from firmware version 310.
After acknowledging an alarm with the reset signal (RS bit), the CIRUS
®
Temperature Controller waits until any
contactor connected has closed the heating circuit again. Only after this waiting time has elapsed measuring
pulses are generated again in order to determine the current ACTUAL temperature and to carry out error diagnos-
tics. This restart delay is 0.2 s by default and can be adjusted with the parameter instance 79. This allows slower
switching contactors to be used.
