GE IS200TCDMS1A 21 dynamic pressure inputs, CCSA or PCB
The CPE330 is shipped with a real-time clock (RTC) battery installed
(see Figure 12). There is no isolation barrier between the battery
and the circuit. This battery will need to be replaced periodically.
Typically, no action is required during initial installation.
Should the RTC battery fail, the CPU date and time will be reset to
12:00 AM, 01-10-2000 at start-up. The CPU operates normally with
a failed or missing RTC battery; however, the initial CPU time-ofday (TOD) clock information will be incorrect.
There are no diagnostics or indicators to monitor RTC battery
status. The RTC battery has an estimated life of 5 years and must
be replaced every 5 years on a preventative maintenance
schedule.
To replace a depleted battery,
1. Power down the RX3i rack.
2. Disconnect cables attached to the CPE330 module, labeling
each for later reconnection.
3. Remove the CPE330 module.
4. Take the CPE330 module to a clean environment.
5. Place the module on a workbench with the heat-sink side
down.
6. With ESD protection in place, remove the four screws holding
the upper side sheet metal in place.
7. Remove the sheet metal. This exposes the circuit board,
connectors and coin battery shown in Figure 12.
8. Using a non-conductive pliers, grip the battery and
simultaneously hold back the retaining clip so it is clear of the
battery.
9. Remove the depleted battery and dispose of it by an approved
method.

10. Install the replacement battery so that the inscribed positive face is towards the green
connector (i.e. downwards as shown in Figure 12).
11. Check that the retaining clip has engaged the edge of the newly installed battery.
12. Replace the sheet metal cover.
13. Tighten all four retaining screws to 0.9Nm (8 in-lbs).
14. Restore the CPE330 module to its original location and secure it in place.
15. Reconnect all cables to their original connectors.
16. Turn power on to the RX3i rack.
17. If needed, set the current date and time via PME or using SVC_REQ 7 (refer to PACSystems RX7i
and RX3i CPU Programmer’s Reference Manual, GFK-2950 Chapter 6).
Note: Battery replacement on CPE305 & CPE310 is different: see Figure 17.
Replacement Real-Time Clock Battery
The replacement battery must be IC690ACC001 from GE Automation & Controls, or an equivalent,
such as Rayovac™ Lithium BR2032 Coin Cell 3V 190mAh -40°C to +85°C

Use of a different type of battery than that specified here
may present a risk of fire or explosion.
Battery may explode if mistreated. Do not recharge,
disassemble, heat above 100°C (212°F), or incinerate.
Caution
To avoid damage from electrostatic discharge, use proper
precautions when performing these procedures:
▪ Wear a properly functioning antistatic strap and be sure that you
are fully grounded. Never touch the printed circuit board, or
components on the board, unless you are wearing an antistatic
strap.
▪ Any surface upon which you place the unprotected circuit board
should be static-safe, facilitated by antistatic mats if possible.
Extra caution should be taken in cold, dry weather, when static charges can
easily build up.
2.2.2.6 Backwards Compatibility of CPE330 with CPU320, CRU320, or CPU315
The CPE330 may be interchanged with a corresponding CPU320/CRU320 with no upgrade to Proficy
Machine Edition (PME) software. Logic and configuration equality in PME are maintained when
storing the same project to either a CPU320/CRU320 or a CPE330.
An Extra Option Module fault is logged in the Controller Fault Table on the CPE330’s slot location after
downloading a CPU320/CRU320 configuration to a CPE330. This indicates that the Embedded
Ethernet interface did not receive a configuration. This fault is expected and does not interfere with
normal controller operation.
Migration of CPU315 applications to the CPE330 is possible with no upgrade to PME by converting
them to a CPU320 application and storing the project to the CPE330.
Versions of PME with native CPE330 support allow either a CPU320/CRU320 or a CPE330
configuration to be stored to the CPE330. When a CPE330 is configured as a CPU320/CRU320,
Ethernet properties cannot be configured. However, the embedded Ethernet ports may be used with
their previously configured IP Addresses or their default IP Addresses if the default IP Addresses were
never changed.
Since CPE330 has no serial ports, any serial port activity associated with the previous
CPU320/CRU320 application needs to be migrated to a suitable rack-based module (IC695CMM002
or IC695CMM004).
