ScreenMaster SM1000, SM2000 and SM3000

Paperless recorders

Replacing the battery

1 Introduction

This publication details the replacement of the battery (B11845)

fitted to the main board of ScreenMaster SM1000, SM2000 and

SM3000 paperless recorders. The procedure must be carried

out by a trained technician.

The battery is non-rechargeable and its only function is to

supply power to the recorder’s real-time clock when the

recorder is isolated from the power supply. It can supply power

to the clock for a minimum of 1.5 years before replacement is

required.

CAUTION

The recorder is vulnerable to electrostatic damage. Wear an

anti-static strap or dismantle the recorder on an anti-static

workbench.

Remove the main board as follows:

1 Isolate the recorder from its power supply.

2 Remove the recorder from its case – see Figure 1.

Note. Refitting is the reverse of removal.

Withdraw the recorder

from its case

See Caution

SM1000 only – disconnect the membrane switch

connector from the main board

SM1000 only – disconnect the

inverter connector from the

main board

Notes.

1. To disconnect the display flex-circuit, it may be necessary to remove the I/O module board in Slot D (if fitted).

2. SM2000 main boards manufactured before March 2005 have a 4-pin tochscreen flexi-circuit and a 4-pin connector block. Main boards

manufactured from March 2005 onwards are fitted with a 6-pin connector block. When reconnecting the touchscreen flex-circuit to a

main board equipped with a 6-pin connector block, ensure it is connected to the 4 pins nearest the front of the recorder.

Caution. When fitting a main board, ensure it

locates correctly in the lugs on the chassis

base.
