MLIM-1 Channel Configuration via Software:
When a MLIM-1 channel is configured as a particular type of input via the
module configuration switches, the configuration will be automatically
detected during the development of a Program Net for the OMP-MODL.
Software input range configuration and utilization of the MLIM-1’s channels
in a Program Net is covered in Chapter 7 and within the Master Icon Listing
in Appendix A.
Input Overcurrent Fuses:
Each channel is protected by a 125mA fuse as shown in Figure 3... -12
(circuit) and Figure 3... -13 (physical location on module). This fuse will
protect the module from overcurrent surges received from malfunctioning or
improperly connected sensors and transmitters.
In the event that a channel on a module quits responding with proper values,
it may be an indication that this protective fuse has blown. The fuse can be
removed from the circuit and checked for continuity with an ohm-meter
and/or replaced with a Littelfuse P/N: 273.125 fuse available from Omega
Engineering Incorporated or many electronic distributors.
