With the following parameters, you can perform a specific control for the hot runners (hot.runners).

The main functions are:

FAULT ACTION POWER

 

You can decide what power to supply in case of broken probe.

 

FAP is the reference power for parameter FAP.

 

Average power is the average power calculated in the last 300 sec.

 

The alarm reset and reference power update take place only at switch-on or after a setpoint change.

 

The alarm is not activated if the control (Ctr) is ON/OFF type, during Selftuning and in Manual. 

HOT RUNNERS CONTROL

POWER ALARM

 

The alarm signals any power changes (OuP) after the 

process variable

 (PV) has stabilized on the setpoint (SP). The 

time beyond which the process variable is considered stable is 300 sec (always on with hot runners).
 

The reference power update take place only at switch-on or after a setpoint change.

 

If the process variable leaves the stabilization band after the first stabilization, this does not influence the alarm.

 

In case of SBR:

- if the PV has not yet stabilized, either the average power over the last 5 minutes or FAP power is supplied (depending on 
the setting of the HOT parameter).
- if the PV has stabilized the average power over the last 5 minutes is supplied.

 Function:

 

If necessary, assign an output (rL.2...6) for the power alarm.

Set the band (b.ST) within which the process variable is considered stable after 300 sec. have elapsed.
Set the band (b.PF) outside which the alarm is activated after time PF.t has elapsed.
 

The reference power is the active power after 300 sec. have elapsed.

The alarm reset and reference power update take place only at switch-on or after a setpoint change.
