HARDWARE<br />
The circuit boards can be<br />
damaged from a discharge<br />
of static electricity. Always<br />
use an antistatic mat when<br />
opening the controller to<br />
protect the circuit boards.<br />
Note<br />
CAUTION<br />
The case top and bottom fit<br />
together with a sealed tongueand-groove<br />
joint. Any damage<br />
— nicks or cuts — to the<br />
tongue, groove, or sealing<br />
gasket prevent the case from<br />
sealing completely when you<br />
close it. Use extreme care when<br />
opening the case to avoid<br />
damaging the joining surfaces.<br />

Select SET PUMP ALARM.<br />
The sampler displays this screen briefly to give you the current pump-count<br />
information. The first line shows you the pump counts tallied since the<br />
counter was last reset. The second line shows the current alarm setting.<br />
To reset the counter to zero, select YES. Always reset the counter after<br />
replacing a pump tube. Select NO when merely checking the current count.<br />
If necessary, change the pump-count alarm setting by typing the first two<br />
digits of the new setting. The sampler accepts entries between 1 and 99. For<br />
example, to increase the count to 1,500,000, enter 15.<br />
Press Stop to return to the main menu.<br />
OPENING THE CONTROLLER CASE<br />
You will need to open the controller case to gain access to:<br />
The desiccant bag that dries the controller’s interior<br />
The battery that provides backup power to the controller<br />
To open the case:<br />
1. Pull the discharge tube and pump tube away from the bulkhead<br />
fitting.<br />
2. Remove the distributor arm by unscrewing the nut that<br />
attaches the arm to the distributor shaft. DO NOT ROTATE<br />
THE DISTRIBUTOR ARM MANUALLY; THIS WILL<br />
SEVERELY DAMAGE THE DISTRIBUTOR DRIVE<br />
GEARS.<br />
3. Remove the controller from the sampler.<br />
4. Open the case by removing the 11 screws that attach the case<br />
bottom to the case top.<br />
Refer to Figure 19 for the location of the desiccant box. To gain<br />
access to the main circuit board and battery, remove the two distributor<br />
connectors and the EMI shield.<br />
