INT69 EXF2 Diagnose BASIC EX

The slim KRIWAN pump protection relay INT69 EXF2 Diagnostics is suitable for temperature monitoring for a pump that is operated in an Ex zone. The protective relay is installed in a control cabinet outside the EX zone. Two relays provide the necessary operational safety. A button and an external input are available as a reset in the event of an interlocked shutdown of the two relays. The run detection function allows monitoring of operating hours and switching cycles in the internal memory. Monitoring of a service interval is also possible in this way.

The INT69 EXF2 Diagnose is a universal and versatile protection relay. The following inputs and outputs are available for monitoring electrical components:

Terminals Inputs and outputs
L/L+, N/L- Supply voltage
T1, T2 Temperature 1 (PTC)
T3, T4 Temperature 2 (bimetal)
E+, E- Leakage (resistance measurement)
B1, B2 Run detection motor
X1, X2 External reset
12, 14, 11 Relay 1 (temperature*)
22, 24, 21 Relay 2 (leakage*)

*Setting ex works

Protection functions and behavior can be flexibly adjusted to the application by parameterization. The INT69 EXF2 Diagnose stores operating and fault data in a non-volatile memory. This data can be read out and evaluated for diagnose. The protective relay is mainly used for the explosion protection of pumps and agitators.
