Obtain burner consent by configuring alarm 1 as inverse deviation with positive hysteresis Hy.P and negative hysteresis Hy.n
7 • CONSENT FOR BURNER AL1
Enable the pre-heating function by setting parameters GS.0, Ht.0, GS.1 other than zero.
It consists of three phases that are activated sequentially at firing:
- Ramp 0 phase
Enabled by setting GS.0 > 0. Starting from setpoint = PV (initial state), it reaches pre-heating set SP.0 with gradient GS.0
- Maintenance phase
Enabled by setting Ht.0 > 0. Maintains pre-heating setpoint SP.0 for time Ht.0
- Ramp 1 phase
Enabled by setting GS.1 > 0. Starting from pre-heating setpoint SP.0, it reaches active _SP set with gradient GS.1
In case of selftuning, the pre-heating function is not activated
