Soft Start During Heater Operation; Channel Control Via Setpoints - Siemens SIPLUS HCS Series Operating Instructions Manual

Time-delayed channel start-up
To reduce the load on the supply system to a minimum, the power outputs are always
switched on in sequence upon start-up. The sequence is as follows:
Depending on the configuration, overall startup can take up to 3 seconds.
If a channel for the POM4320 is switched off during operation (setpoint 0%) and then
switched on again, switch on takes place immediately.
A softstart can be configured for startup with the POM4320 Highend.

Soft start during heater operation

If a channel is switched off during operation (setpoint 0 %) and then on again, this switch-on
can take place via soft start if configured accordingly.
9.3.6

Channel control via setpoints

It is possible to control the channels using only the setpoints in the cyclic data. In this mode,
it is not necessary to combine channels into fields and to assign field setpoints.
The operating mode setting in the cyclic data (production, standby) is not relevant in this
case.

1 The user has specified the field setpoints and the channel setpoints.
2 The user activates the required operating mode
3 The user switches the heating "On"
4 Several POMs are activated with a time offset in ascending slot order
5 Within each POM, the channels of a phase are also started in sequence. The channels of
the three phases are controlled "simultaneously" per POM4320.
With the POM4320 Highend, the 6 channels are started one after the other regardless of
the phase.
