CHECKING

1) Terminal wiring:  Check that all cables are correctly con-

nected according to the connection diagram.

2) Input:  Check that the input voltage is within 0 – 100% of 

full-scale.

  If the thermocouple/RTD or its extension wires are bro-

ken, the output goes over 100% (below 0% with down-

scale) due to the burnout function.  Check leadwires in 

such a case.

3) Output:  Check that the load is within the permissible 

limit including wiring resistance.

Load Resistance (Ω) =

Supply Voltage (V) – 9 (V)

0.023 (A)

 

(including leadwire resistance)

PC CONFIGURATOR SOFTWARE

To calibrate the signal to match with a receiving instrument 
or to change the factory-set configurations, use the PC Con-
figurator software installed on a Windows PC via a HART 
modem connected to the PC.
The PC Configurator software is downloadable at M-Sys-
tem’s web site: http://www.m-system.co.jp

 

USING THE HART COMMUNICATION

Refer to the HART Setup Manual (EM-7501-B) for setting 
up the unit using the HHC.  For operating an HHC (Hand- 
Held Communicator), refer to its instruction manual.
