DIP Switches
Fuses
The M3200, M3200LTR and M3300 ship from the factory with fuses NOT
installed. Install the appropriate supplied fuse to match the voltage being used.
The M3224 has a resettable fuse to match the required 24V power supply.
DIP Switch / Fuse Location
*Indicates factory setting.
** DIP switches 1and 2have no affect on M3200 and M3224.
This module must be set up for the actual supply voltage.
If power supply is 115V
Step 1 Set power selector in position 115V
Step 2 Mount fuse 80mA T
If power supply is 230V
Step 1 Set power selector in position 230V
Step 2 Mount fuse 50mA T
Note: Power selector and fuses are
found under cover on top of module.
Caution
Failure to follow instructions
may result in equipment
damage or personal injury.

CALIBRATION
Zero Point
1Connect power and load cells to M Series Amplier as described in
WIRING section.
2With web removed and no tension on load cell roller, adjust ZERO
potentiometer using a voltmeter:
Note: A remote meter can be used to zero the 3200/3224. Connect
meter (see WIRING section) and adjust ZERO potentiometer until
meter reads 0.
Calibration
3Select a weight that is at least 25% of the full scale tension range expected
to be present on the load cells.
4Suspend the weight from a non-elastic rope or strap that has been fed
through the rollers of the machine exactly as the feed material will be in the
application. It is important that the rope match the wrap angles on the
tension sensing roller that will be used when the machine is running.

CALIBRATION
5Rotate all of the rollers the rope wraps around in the direction of the weight.
This is done to counteract friction forces on the rope to the rollers, which
may cause inaccurate readings.
6Adjust potentiometer(s) using a voltmeter:
*
Output voltage value = V. Calculated by the following formula:
V = (calibration weight/CAL. full-scale value) x 10 volts
Note: A remote meter can be used to calibrate the 3200/3224.
Connect meter (see WIRING section) and adjust CAL. potentiometer
until meter displays calibration weight.
7Remove weight. Output should return to 0. If not, repeat steps 2, 5 and
` 6 while verifying calibration weight. Repeat as necessary until 0 and
calibrated weights are accurate.

Alarm Level Adjustment
Apply a weight to the tension sensing roller equal to the value that should
activate the alarm. Adjust the ALARM potentiometer until the ALARM LED
lights up. Alarm output will be high (+24 V) whenever tension drops below
the alarm level.
