Control Adjustments
CH 1 Delay, CH 2 Delay:
Potentiometer adjustment which delays the actuation
of Channel 1 or Channel 2 to prevent Clutch-Brake
overlap. Range Adjustment: 0.1 to 7 milliseconds.
CH 1 Torque, CH 2 Torque:
Potentiometer adjustment for steady-state output
voltage of Channel 1 and Channel 2. Range adjust-
ment; 0 to 6 volts DC.
CH 1 Overexcitation, CH 2 Overexcitaiton:
Potentiometer adjustment for adjusting overexcitation
time period for Channel 1 and Channel 2. Range
adjustment: 2 to 14 milliseconds.
LED Indicators
CR 102, CR 302:
Indicates when Channel 1 or Channel 2 output is
actuated. CR 205, CR 405:
Indicates operation of overexcitation pulse for
Channel 1 or Channel 2 when switched.
CR 12: Input LED on “in” terminal. On when input
terminal is pulled low.

The basic control provides both 12 volts DC for use with
the 12 volt DC compact scanners, and 24 volts DC for
use with the MCS-638 color Mark Scanner. The MCS-624
Register Mark Scanner may be used also, when the 4.8
volt Power Board is used.
It should be noted that the maximum rated output for the
Clutch-Brake is limited to 4.4 amps. If applications require
use of Clutch-Brakes whose ratings exceed this maximum
limit, the factory should be consulted.
Installation
Mounting
Mount the Control with the terminal strip positioned
toward the top. This allows the transformer heat to rise
away from the other components.
Wiring
1. Connect clutch and brake to each pair of
respective Channel 1 and Channel 2 terminals
as required.
2. Connect AC input to the AC input terminals.
Set AC selector switch to the desired range
120 VAC or 240 VAC.
3. The earth ground terminal provides for connection of
the transformer core to earth ground.
4. Connect input switches per appropriate figure
for type switching desired.
a. For Basic Control Switching, use Figure 2.
b. For Bag Logic Module, use Figures 3 & 5,
or 4 & 5.
c. For Stitch Logic Module, use Figures 6 & 7.
5. For external LED indicator connection, connect as
follows:
Initial Checkout
Basic Control without interface options, per Figure 2.
1. Apply AC power to MCS-131 Control.
2. With inhibit terminal (2) grounded, control
should power-up channel 2 on.
3. Ground input terminal (8), control should
switch to channel 1 on, and “in” LED should be on.
4. Remove ground from input terminal (8), control
should switch back to channel “on” and “in” LED
should be off.
Stitch Logic Board, part number 6040-448-017
(optional). Open collector compatible, device rating:
15 volts DC, 20 ma. minimum, maximum saturation
voltage ≤ 0.7 VDC.
Provides for start, stop, and inhibit functions. See
Figures 6 and 7.
OPTIONAL COMPONENTS: 4.8 volt power board,
part number 6040-448-014 (optional). Provides for
4.8 volt DC @ 1.0 amp output for operating MCS-
624 Register Mark Scanner.
Cover, part number 6040-448-015 (optional).
Provides for optional enclosure of basic MCS-131.
Applications
Typical applications for overexcitation include cutting
labels after printing, separating bags after
manufacture, filling, and other precision applications.
System capabilities are expanded by using the
optional logic boards with the basic control.
