Feedf - Feedforward Power; Dead.b - Deadband; Fault - Fault Action Power; Grad.i - Setpoint Gradient In Increase - gefran 850 Installation And Instruction Manual

4.14.25. FEEDF - Feedforward power

Acronym
FEEDF PID.1 (o PID.2) FEEDFORWARD
The parameter shows and sets the feedforward power value, i.e., the value that generates an additional factor at the
control output based on the setpoint value.
Unit of measurement:
Options: -100.0...100.0

4.14.26. DEAD.B - Deadband

Acronym
DEAD.B PID.1 (or PID.2) DEAD BAND
The parameter shows and sets the deadband.
The deadband is symmetrical to the setpoint. If the process value (PV) stays in this band, the control output keeps the
required power value constant.
Unit of measurement:
Options: 0...999

4.14.27. FAULT - Fault action power

Acronym
FAULT PID.1 (or PID.2) FAULT ACTION POWER
The parameter shows and sets the fault action power, supplied if the sensor is broken.
Example
If Cntr = HP.CON (Proportional Heat, ON/OFF Cool), the option is On, OFF, 0.0...100.0, i.e., if you set FAULT = On the
cooling output will be ON in case of fault.
Unit of measurement:
Options: -100.0...100.0
On, OFF

4.14.28. GRAD.I - Setpoint gradient in increase

Acronym
GRAD.I PID.1 (or PID.2) SETPOINT GRADIENT IN INCREMENT
The parameter shows and sets the gradient used when the setpoint value is increased.
If the parameter is "0.0" the gradient is disabled.
Unit of measurement:
Options: 0.0...999.9
