7. A Relay puller is provided inside the rear of the case when the Unit is deliv-
ered. Use the Relay puller to pull out the Relay as shown below. Insert a new

Using the Relay puller,
pull the Relay up and out
of the socket.
8. Reassemble in reverse order of assembly.
Caution Check the pin arrangement before inserting a new Relay into the socket. Pins
can only be inserted one way, so do not try to force them if they do not go in easily.
Applying too much force can bend the pins and render them unusable.
7-4 Batteries
DANGER Batteries can burn, explode, or leak. Absolutely do not short-circuit across the
terminals, attempt to recharge batteries, or take them apart, heat them, or
expose them to fire.
When the battery is nearly discharged, the ALARM indicator blinks and the mes-
sage “BATT FAIL” appears on the Programming Console. When this occurs, re-
place the battery within one week to avoid loss of data.
The normal battery service life is five years at 25°C. The service life will be short-
en if used at temperatures higher than that.
The Battery Fail Flag is allocated to 25308 for the C200HS.
The battery comes together with its connector as a set. To replace the Battery
Set (C200H-BAT09), follow the steps below. The entire replacement must be
completed within five minutes to ensure that the data will not be lost.
1, 2, 3... 1. Turn OFF the power to the PC. (If the power was not already ON, turn the
power ON for at least one minute before turning the power OFF.)
