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

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