Description
 

The Macromatic TCP7G100 is an over temperature & seal leak relay. This 11 Pin plug-in relay has an input voltage of 24V AC/DC. It is made to monitor for leaks in submersible pump seals, as well as over temperature issues. It has an output of 7A SPDT and is made for pumps that detect leaks with resistance sensing. The LEDs on top of the relay indicate the status. It can connect in three different ways including one probe to ground, two probes to ground, or probe to probe. Uses 70170-D octal socket. Note: Image is for reference, actual part may differ

The relay is connected to a thermal switch in the pump motor to check for over temperature problems. The resistance sensing probe is also connected to the relay to check for seal leaks. There is one output contact for overheating and one for seal leaks, which are isolated. The over temperature point is set at 5K ohms, and the seal leak sensitivity ranges from 4.7K to 100K ohms. When the input voltage is introduced, and there are no errors, the over temperature relay is energized and the seal leak relay is not. The LEDs are green. If overheating occurs, the over temperature relay de-energizes and the TEMP LED is red. Once the overheating has been corrected, the relay resets automatically. In the event of a seal leak, when the resistance goes below the sensitivity point on the relay, the seal leak relay energizes & the LEAK LED is red. The sensitivity point is adjustable using the low profile knob in top of the relay.
