Using the OMP-MODL
2-11
RTC / Memory Backup Battery
The OMP-MODL utilizes static ram for internal data storage which requires a
constant power supply to maintain its memory. Similarly, the Real Time
Clock (RTC) that keeps track of the date and time within the OMP-MODL
runs continually whether the main power switch is ON or OFF.
When the main power is ON, the memory and RTC draw their power from
the D-Cell batteries (or a connected external power supply). When the main
power is switched OFF, power for memory and the RTC automatically
switches to a small coin type lithium cell that is mounted on the main OMP-
MODL circuit board (Figure 2... -7).
This cell will provide power for the RTC and memory for approximately one
year. Any time that the OMP-MODL main power is ON extends this lifetime.
At any time, the approximate state of charge of the lithium cell can be
displayed on the LCD under the SYSTEM STATUS / SUPPLY VOLTAGES
menu or from a serially connected PC running HyperWare and a
Status
Query
command. For lithium cell replacement procedure, refer to Appendix
D.
MLAD-1 M
ODULE
Overview
The MLAD-1 module contains the Analog to Digital converter, General
Purpose Digital Input channel circuitry, Cold Junction Compensation
circuitry, and four channels of analog input. This module plugs into the top
of the MLCPU-1 module (or MLIM-5 if so equipped) and is required in all
OMP-MODL systems.
