By pressing the [MELT] key, pass to
• pre-heat mode, if the threshold P8 has still to be exceeded
• preservation mode if threshold P8 has already been exceeded
When the temperature reaches the work set-point P2 for the first time, the buzzer rings for
the time established with parameter P21. Signalling is re-enabled at every start and every
SP modification.
4.5. Minimum times for outputs switch-over
During P.I.D. type regulation, minimum times are envisioned for outputs switch-over:
• Output activation: if the time calculated for output activation is lower than P5, the
output is not activated.
• Output deactivation: if the time calculated for output activation is over P4-P9, the
output is deactivated.
4.6. Timer
The timer setting can vary between 0 min and 99 min. When the count is in progress, the
min LED flashes. The count is displayed in minutes. When 1 minute is missing to the end,
the count is displayed in seconds.
Ten seconds before the end of the count if P24 is not null, the buzzer is activated for a
time period equal to P24 and the display shows the residual time in seconds, until the
count expires and the buzzer no longer rings. When both of these conditions are satisfied,
the display goes back to being that pre-defined (e.g. probe 1)
The buzzer can be silenced by pressing a key. If P24=0 the buzzer is not activated. If
P24= -1 the buzzer is activated until silenced manually.
4.7. Fans
If the temperature detected by the board probe exceeds the threshold established with
parameter P23, output 2 is activated. The hysteresis is equal to 2°C/4°F.
If the probe on the board is in error conditions, the output is always active
4.8. Board temperature alarm memorisation
If the temperature detected by the board probe exceeds the threshold established with
parameter P22, the buzzer rings, the L5 alarm LED switches on and the Ht message
appears on the display alternating with the default display. The board memorises the
maximum value reached by the probe in alarm situation. The data memorised cannot be
deleted in any way.
If the alarm is in progress, pressing any key allows to silence the buzzer, the Ht message
disappears as soon as the temperature drops below P22.
If the temperature drops below P22, pressing any key allows to silence the buzzer and
make the HT message disappear.
