CHAPTER
RTM Control Box Programming:
Quick Start
1. Turn power to the Control Box on
2. To set the Preset (number of counts) press or key once. Use the key to
increase that column to the desired number. Use the key to select the desired
column; you must set each of the columns, one’s, ten’s, and hundred’s separately.
3. When finished entering the desired number into the Preset press the key once to
store the number.
Note: Pressing the key will reset the counter to zero.
Calibration & Setup:
The Meter will take counts from a sensor assembly attached to the pump assembly. The
sensor assembly will send the meter a given number of counts per stroke depending on the
sensor assembly installed. The more counts per stroke provided to the meter the more
accurate it will be.
There are a couple of methods of calibrating the Preset for your part.
Set the counter at the maximum setting or very high for the first operation. Once you have
filled your part with the desired amount of material note the number on the display. This
number becomes your Preset. Enter the number into your Preset, when the counts reach that
number the pump will shut off and the display will reset to zero.
Another method to determine your Preset is to
1. Test sample resin by cycling the resin pump 10 full up and down strokes and note the
number that appears on the display.
2. Weigh the resin sample that was discharged from the pump.
3. Divide the desired amount (weight) of resin required to produce the part by the amount
(weight) of the resin sample discharged in the step above (step #2)
A (desired weight)
= C
B (resin sample weight)
4. Multiply the number noted in step #1 by C the number derived in step #3. This becomes
your Preset, enter this number into your Preset, when the counts reach that number the
pump will shut off and the display will reset to zero.
