Operating manual

MSF 220 SE

Application

The PTC-resistor trip device MSF 220 SE monitors the winding temperature of machines and
equipment. Signals, that can be used as ”early warning" or ”malfunction" (switching-off), are
transmitted as soon as the admissible limit temperature is exceeded.
Two PTC-circuits can be connected to this unit. The integrated rise-delay time ensures a
reliable mains voltage build-up.

Function

* 2 PTC resistor circuits, 1 to 6 PTC each (max. cold resistance of circuit 1500Ω each)
* p

otential-free contact for alarm 1
* potential-free contact for alarm 2
* voltage of pin 3 is connectet to pin 1 with a time delay of 2 sec., replacing an additional

timing relay.
* alarm 3 for check of relay K3
* LED´s signal state of relays K1 and K2
* relay K3 picks up time-delayed

Note

Thanks to the delayed switching-on of the error message (approx. 2 s) after the switching-on,
this device is especially suitable where an auxiliary voltage is not available and the secondary
voltage of the monitored transformer is being used. The MSF-200 SE can furthermore be used
advantageously when combining it with operating current releases. For additional devices, the
control voltage is available at terminal 1 time-delayed. In case of a breakdown of the supply
voltage, the control voltage is available at terminal 7 and can be used as a message.
(Attention! This message will also be given for approx. 2 s. after switching-on.)

Functional description

PTC-circuits in closed-circuit current principle. When the closed-circuit current flows, both
output relays K1, K2 are picked up. Approx. 2 sec. after switching on supply power, relay K3
picks up time-delayed, closing the contact circuits at terminals 31, 14 and 31, 24. As soon as
the temperature of the early warning has been reached, relay K1 releases (terminal 31, 12
closed), the alarm 1 is given. If the temperature of malfunction is reached, also relay K2
releases (terminal 31, 22 closed). This alarm 2 can be used to switch off the equipment. If the
temperature drops to approx. 5 °C below the temperature of malfunction or early warning, the
relays K1 and K2 resp. are switched on again.

Installation - Putting into operation

The plug base can be mounted either with

* 35 mm mounting rail according to EN 60715 or
* M4 screws

Wiring directly to plug base

* Connect wires as per wiring scheme
* Plug in electronics and fix with knurled screw

Attention!
Do not plug in device alive nor detach it from socket.

When installing the device into the switch-gear cabinet, please observe the max.
admissible temperature. Care for both sufficient clearance to other devices or sources
of heat or enough forced draught.

Before switching on make sure that the operational voltage Us of the lateral type plate
and the mains voltage are the same.

* Apply mains voltage to terminals A1 and A2
* When device is ready for operation, relays K1 and K2 switch on immediately, the LED’s

are off. After approx. 2 s. relay K3 picks up, terminals 31-14, 31-24, 31-34 are

connected.
* Relay K1 releases as soon as the input at terminal T11, T12 becomes high- resistive.
* Relay K2 releases as soon as the input at terminal T21, T22 becomes high-resistive.
* Relay K1, K2 pick up as soon as the inputs at terminals T11, T12 and T21, T22 become

low-resistive.
* Relay K3 releases first, as soon as the supply voltage is switched off.

Trouble-shooting and remedies

* Relays are not switched on.
Check whether supply voltage Us at terminal A1, A2 is available and corresponds to the

voltage indicated on the lateral type plate of the device.

* LED´s light up continuously.
Check whether PTC’s at terminals T11, T12 and T21, T22 are connected correctly. Both

PTC’s must be connected and low-resistive.

Attention! Check PTC’s only with measuring voltages of < 2.5 V.

* In case of any other malfunctions, replace device and send it in together with a

description of the occurred malfunction.
