3.11.7 Motor PTC
Terminal block J7 is for a PTC (positive temperature co-efficient) motor thermistor. This input is designed to use standard DIN 44081 or
DIN 44082 thermistors. The specifications of the input are as follows;
- Trip resistance 3.5K, ± 300 Ohms
- Reset resistance 1.65K, ± 150 Ohms
- Open terminal voltage is 15V
- PTC voltage at 4Kohms = 8.55v. (>7.5V)
- Response time adjustable between 1 and 5 seconds
- Maximum cold resistance of PTC chain = 1500 Ohms
An example of the thermistor wiring is shown below in Figure 19.
See Also Motor PTC Trip Time (PFN 27) on page 86.
3.11.8 RTD Module Connector
Connector J1 is for the connection of Benshaw Remote RTD Modules. These modules can be mounted at the motor to reduce the length
of the RTD leads. The connector is a standard RJ-45. The wires connect as follows;
4 - B(+)
5 - A(-)
8 - common
