3 Application and short description ZIEHL PTC-thermistor relays protect motors, transformers, machines and equipment against thermal overload. With ZIEHL PTC Sensors MINIKA ® applied they offer best solutions for nominal response temperatures 60°C…180°C. ZIEHL PTC-thermistor relays are designed for PTC-sensors according to DIN 44081 and DIN 44082. Therefor sensor and relays are exchangeable.
With bridged terminals Y1, Y2, the reclosing lock function is disabled and a device type MSR works like a device type MS. MS types switch on automatically when the temperature has decreased approx. MSR220K 13000-0701-00 Page 3 / 8 www.ziehl.de...
Attention! Trip relays type MSR220K with electronic reclosing lock switch on automatically by return of the supply voltage. To automatically prevent start-up the applicant must install additional components or monitor the power supply lines.
With no PTC sensor connected the PTC Trip Relay must release. The voltage at terminals T1-T2 must be approx. 8 V. In case of any other malfunctions, replace device. Please add a description of the occurred malfunction when sending back for repair. MSR220K 13000-0701-00 Page 5 / 8 www.ziehl.de...
