Advanced Program
Opened/Not connected SJ1 jumper mode
1. Adjustment with the use of four trimmers. Trimmers allow to set PID
parameters, as well as the temperature setpoint.
2. The system detects a lack of connection with the thermistor and then
switches WARNING LED on. As long as the connection is lost, the driver will
not take any action and the open collector output is grounded.
3. If the measured temperature exceeds an overriding limit of +70°C in the NTC
10k versions (+120°C in the Advanced -100/+100 version), the Peltier
module is switched off.
4. If the measured temperature is out of Tmin...Tmax range, the WARNING LED
is ON and the open collector output (OC) is connected to ground. The PID
regulator works normally (unless the overriding limit mentioned before is
exceeded). In the Advanced versions, when the SJ1 jumper is open, Tmin
and Tmax have fixed values: 0°C and 70°C respectively in the Advanced NTC
10k version, and -120°C and +120°C respectively in the Advanced
-100/+100 version. In the Advanced versions, Tmin and Tmax can be set by
the user (through the serial connection) and the settings become valid when
the SJ1 jumper is closed.
