GETTING STARTED

  1.  Install the control as described on page 2.

  2.  Wire the control following the instructions on pages 

      3 through 5. Page 3 contains basic wiring for the 

      control. If using the Series MPC’s transmitter power 

      supply follow the additional directions on page 

      4. Wiring instructions for the 232 and 485 series 

      communication options is included on page 5.

  3.  Familiarize yourself with the front key pad functions 

      and read the menu structure prior to starting the 

      programming process. A programming chart with 

      the menu structure and spaces to write your 

      programming values is included on page 14.

  

This 

      chart can be a helpful tool to save time in 

      programming. For further assistance programming 

      examples are included on page 15.

MODEL IDENTIFICATION

Model MPC - 

Input Ranges

Process Input Types

The  0-20  mADC,  4-20  mADC,  0-10  VDC,  and  2-10 

VDC  inputs  are  fully  scalable  from  a  minimum  of  100 

count span placed anywhere within the range of -1999 

to +9999. Decimal point position is adjustable from the 

zero place (9999), tenths (999.9), hundredths (99.99), or 

thousandths (9.999).

Installation

Mount the instrument in a location that will not be subject 

to  excessive  temperature,  shock,  or  vibration  (see 

Specifications  for  specific  tolerances).  All  models  are 

designed for mounting in an enclosed panel.

Select  the  position  desired  for  the  instrument  on  the 

panel.  Prepare  the  panel  by  cutting  and  deburring  the 

required opening.

From  the  front  of  the  panel,  slide  the  housing  through 

the cut out. The housing gasket should be against the 

housing flange before installing.

From the rear of the panel slide the mounting collar over 

the housing. Hold the housing with one hand and using 

the other hand, push the collar evenly against the panel 

until the springs are compressed. The ratchets will hold 

the mounting collar and housing in place.

It  is  not  necessary  to  remove  the 

instrument chassis from the housing 

for  installation.  If  the  instrument 

chassis  is  removed  from  the  housing,  you  must  follow 

industry  standard  practice  for  control  and  protection 

against  Electro-Static  Discharge  (ESD).  Failure  to 

exercise good ESD practices may cause damage to the 

instrument.
