sheet 3 of 4
Type: MSF 220 SV
Installation - Putting into operation
The plug base can be mounted either with
*
35 mm mounting rail according to DIN 50 002 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. Generally recommended mininum
clearance: 2 cm.
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 11 and 12.
*
When device is ready for operation, relays “ALARM1” and “ALARM2” switch on
immediately, the LED’s are off. After approx. 2 s. relay “ON” picks up, terminals 3 -
4, 3 - 5 are connected.
*
Relay "VENT" picks up, as soon as the input at terminal 7, 10 becomes high-resistive.
*
Relay "VENT" releases 20 min. after the input at terminal 7, 10 becomes low-resistive.
*
Relay “ALARM1” releases as soon as the input at terminal 8, 10 becomes high-
resistive.
*
Relay “ALARM2” releases as soon as the input at terminal 9, 10 becomes high-
resistive.
*
Relay “ALARM1”, “ALARM2” pick up as soon as the inputs at terminals 8, 10 ; 9,
10 become low-resistive.
*
Relay “ON” 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 11, 12 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 7-10, 8-10 and 9-10 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.
