Unit status and new set points can be Series: communicated by serial communication. Mode changes, however, MRT= 6 digits, counter / ratemeter must always be made on the front panel. Data is transmitted at with presets and scaling. -
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 Minitrol
WIRING MINITROL 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 RF 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.

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). LOCK PROGRAM - This will lock the program and allow the presets to be changed when the unit is in the LC PRG lock mode. -
Page 14: Calculating Scale Factors
CALCULATING SCALE FACTORS There are two separate dividing scale factors, one for input "A" and one for input "B". The factor to enter is the number of pulses per the desired unit of measurement. The factor ranges from 0.0001 to 99999. The factor is the same for rate and count on input "A". -

Mode changes cannot be bit and is used to help check if the transmission is correct. done through the front panel. - Page 23 SERIAL INPUT COMMANDS: The input impedance of RS232 is 3KΩ to 7KΩ worst case. To get a unit on line you must address it by it's device number. The terminal addressing the unit must be capable of driving This is done by typing DXX(S), XX= device number. The unit all loads in the loop.
