DIP SWITCHES SETTINGS FOR PT100/THERMISTOR INPUTS DESIGNATION
The following must be done in order to set the right sensors connected to the TPR-6:
1. Set the sensor type in the TEMPERATURE SETTINGS page. Refer to section
6.1 page 10.
2. Set the dipswitches as shown here after.
In order to change the position of the dip switches the main PCB (In all models) and the input PCB
(In TPR-6/14 only) should be dismantled.
Note:
Take all safety precautions to prevent electrical shock or damage to the TPR-6 before
dismantling the TPR.

Close look on dip switches
S1&S2
PT100/Thermistor inputs T1-T6 (All models) are designated via dip switches 1-6 on the main PCB.
PT100/Thermistor inputs T7-T14 (TPR-6/14 only) are designated via dip switches 1-8 on the input PCB.
Two sets of dip switches are on each PCB – marked S1 and S2. Each PT100/Thermistor input is designated
by the position of two dip switches – one in S1 and the second in S2. Both dip switches must be in the same
position.
When dip switches are in ON position, the input is designated as a Thermistor input (PTC type or NTC type
should be programmed via the key pad).
When dip switches are in Off position the input is designated as PT100.
For example, in order to designate PT100/Thermistor input T6 to Thermistor PTC put dip switch no. 6 in S1
and dip switch no. 6 in S2 on the main PCB to its ON position. After doing so program this input as a PTC
input via the key pad.
In order to designate PT100/Thermistor input T8 to PT100 put dip switch no. 2 in S1 and dip switch no. 2 in S2
on the input PCB to its OFF position. (Note that dip switches no. 1 in S1 & S2 are for PT100/Thermistor input
T7).
