Promass 80, 83, and 84
When connecting the Promass 84 (does not apply to the Promass 80 or 83 models) to a microLoad.net it is impor
-
tant that the “Line Monitoring” function on the Promass 84 be disabled. This is because the pulse input circuitry of
the microLoad.net requires the input pulse “off” voltage to be less than one volt (and the “on” voltage to be greater
than 5 volts). If the “Line Monitoring” on the Promass 84 is enabled, the “off” voltage of the pulses will be greater
than one volt and therefore will not be counted by the microLoad. There are three jumpers on each of the frequency
output submodules on the I/O board that enable/disable the “Line Monitoring” function. The factory default is to en-
able “Line Monitoring”. Follow the steps from section 6.4.2 of the Proline Promass 84 Operating Instruction – Bulletin
MN0M032 to enable/disable this function.
Use this table to determine if the Promass can be wired for single or dual pulse output and the terminal number
corresponding to each unique model. The wiring diagrams are shown on the following pages.
