6.Note for mounting
1.Insert wire in the winding wire slot of the motor,make it tidy, and then mount the PTC thermistor in the coil of motor(as shown in figure).
2.White mounting,do not hard beat or press the sensing area of the thermistor for fear that the internal precise structure of the product might be damaged.
3. While mounting,do not extremely hard pull the outgoing line of the product for fear that the outgoing line might be pulled apart.
4.Before connecting,read the technical information about PTC temperature control module(the former GRB motor overheat protector) for fear that the thermistor might be damaged.
5.Securely connect the outgoing line in the specified connection position.

| Resistance value is too high(measure resistance of the outgoing line by Ohm band of an AVO meter,the resistance value of a single line is higher than 100 Ohm at 25℃) | 1. The lead of the thermistor opened a way or was in a bad contact. 2. The thermistor was damaged. | 1.Check the lead of the thermistor whether open or not,or in the bad contact 2.Replace the themistor |
| Resistance value is too high(measure resistance of the outgoing line by Ohm band of an AVO meter,the resistance value of a single line is higher than 20 Ohm at 25℃) | 1.The lead of thermistor was in short circuit; 2.The thermistor was damaged | Check the lead of the thermistor is in short circuit or not,and connect it. 2,Replace the thermistor |

9. OPERATION
PTC thermistors exhibit very high sensitivity over a narrow temperature band. For temperature measuremen in this range, NTC thermistors are easier to measure and more accurate. PTC thermistors are especially suited as temperature sensors for monitoring the windings of electric machines, and also for use in simple fail-safe circuitry. When a given temperature (nominal response temperature qNAT) is exceeded, the circuit can be switched off through a relay or amplifier, since the PTC-sensor will have an extremely high ohmic value in the region of its response temperature. This will have the same effect as a break in the circuit or a failure of the thermistor.
10.INSTALLATION TIPS
For PTC temperature sensors in electrical windings:
- the thermistors can only be inserted in the windings before impregnation - it is advisable to embed one in each phase, if possible in the centre of the coil generating most heat, and generally on the outflow side of any air movement
- air inflow onto the temperature sensor will interfere with heat transfer
- if using varnish/lacquer which is not chemically neutral, suitability tests must be undertaken by the customer
- WARNING! It is very important that the sensor must be installed parallel with the copper of the winding, so that the PTFE leads can assume the form of the rest of the winding and thereby retain the high- voltage resistance rating.
