WARNER ELECTRIC
MCS202-E1 / MCS202-E154 / MCS202-EC1
Every MCS202-E version has the same electrical characteristics and performances
MCS202-E1
Standard monoblock control unit (operator controls located on the front panel)
MCS202-E154
Same as above but constructed for IP54 protection - Non used receptables should be closed with a sealed
dummy connector
MCS202-EC1
Printed circuit board version (power switch, power input and brake switch to be provided and wired by the user.
Also used as replacement part for above models.

Technical information
The electronic circuit utilises a single +15 VDC power source. The supply voltage for the sensor is +15 VDC, the sensor signal should
be minimum +3 VDC and maximum 10 VDC. When the Warner Electric sensor MCS605-E is used it should be operated within a
+/–30° band around the operating position. The input receptacle SK2 is compatible with the connector on the MCS605-E cable
included in the MCS-KIT.
In order to ensure correct starting and stopping of the machine, the DRIFT STOP function available on auxiliary receptacle SK3 has to
be wired to an external switch. When the unwinder is not running the DRIFT STOP function should be activated by closing the con-
tact.
In the event that the dancer arm movement provokes reversed results (full braking with minimum loop and no braking with maximum
loop) the sensor polarity has to be reversed. A sensor polarity switch is present at the rear of the MCS605-E sensor. When other types
of sensors are used, then SW3 on the printed circuit board should be reversed.
For applications where the diameter ratio (ratio between maximum and minimum diameter) exceeds 8:1, we recommend to use the
"change over gain" function by closing S3 from middle to small Ø.
All inputs in the auxiliary connector SK3 and brake power are optically isolated from the +15 VDC supply voltage.
