Page 7: How To Mount The Unit
HOW TO MOUNT THE UNIT The unit is designed to be mounted with a gasket providing a water tight seal. Two mounting brackets are provided to secure the unit to the panel. A panel less than .1" may distort if the clamps are screwed too tightly. Slide the body of the unit through the rubber gasket. -
Page 8: Wiring Guidelines
WIRING GUIDLINES The rear terminal contains 12 screw terminals for connecting #14 to #28 gauge wire. The unit is controlled by a microprocessor and, therefore, an electrically "noisy" environment could cause operating problems. The input power line should not be common to power lines for motors, pumps, contactors, etc. The unit is designed to be immune from line or transient voltage interference. - Page 9 CONNECTING AC / DC POWER NOTE: Connect power only after other connections are finished. Do not touch the live AC power terminals! The unit has been designed with an isolated AC input. Thus, polarity is not a concern for the AC input. The chassis is plastic, therefore earth ground is not used.

ABBREVIATION DESCRIPTION FACTOR SCALING FACTOR - Enter the 5 digit dividing scale factor (K-Factor) for the total input (Input A). DP F A DECIMAL POINT FOR FACTOR A (rate) - Enter location of decimal point for the rate scaling factor by pressing the button under the digit where the decimal is desired. -

LOCK - This portion of the menu allows you to: 1) lock the program (presets are still accessible) 2) lock all (presets and program are locked). LC PRG LOCK PROGRAM - This will lock the program and allow the presets to be changed when the unit is in the lock mode. -
Page 14: Calculating Scale Factors
CALCULATING SCALE FACTORS There are two separate dividing scale factors, one for rate and one for total. The factors are entered as the number of pulses per the desired unit of measurement. The factor ranges from 0.0001 to 99999. Because the “units per second”, “minute”, “hour” or “day” are field programmable from the keypad, scale factor calculations for the ratemeter are easy. -

OUTPUT WIRING The following diagrams detail the connection of the relay and analog output options. Each relay consist of a form A contact (Normally Open). NPN transistor or Normally Closed contacts are available with solder jumpers (see Jumper Options). ANALOG OUTPUT The analog output can be selected to output 4-20 mA or 0-20 mA and can be selected to track the rate or total. -
Page 21: Analog Output Option
ANALOG OUTPUT OPTION Description: SWITCH 4: Calibrate (normally off) An optional 4-20mA (0-20mA) output has been added to the Minitrol Switch 4 is used for calibration. Calibration is done at the factory series. The output can be programmed to track rate or total. This and should not be needed (see SWITCH 1 to enter high and low feature is available by adding suffix A to the part number. -
