5.
Separate the front and rear housings in accordance with “Separation of
Front and Rear Housings” on page 8-5.
6.
Connect the pump to a 115 VAC, 60 Hz AC power source.
7.
Disconnect and reconnect the slide clamp sensor connector:
Q
Pump 1: CN803
Q
Pump 2: CN804
8.
Connect a voltmeter to:
Q
Pump 1: CNTEST-pin 3 and CNTEST-pin 5 (GND)
Q
Pump 2: CNTEST-pin 1 and CNTEST-pin 5 (GND)
9.
Enter Automatic Test Mode 1 by pressing and holding the
CLEAR TOT
VOL
and
1
keys while pressing the
ON-OFF/CHARGE
key.
Note: If the potentiometer in the following step cannot be easily moved from its
present setting, it has been sealed with Loctite 211 or 222 or Red Glpt Var-
nish. To loosen the adhesive, apply one or two drops of isopropyl alcohol to
the affected potentiometer and wait one minute before trying to move it again.
10.
Insert the slide clamp (part no. 030801011) and close the door. Verify
that the voltage at the appropriate test point is 0.25 V or less.
Q
If the voltage is less than or equal to 0.25 V then proceed to the next
step.
Q
If the voltage is greater than 0.25 V, attempt to adjust the voltage by
turning the potentiometer fully clockwise:
•
Pump 1: VR805
•
Pump 2: VR803
Note: Replace the safety/slide clamp assembly when it cannot be calibrated
(“Replacement of Safety/Slide Clamp Assembly” on page 8-19).
11.
Without the slide clamp inserted and the door closed, verify that the
voltage at the appropriate pin is 4.2 V or greater:
Q
Pump 1: CNTEST-pin 3 and CNTEST-pin 5 (GND)
Q
Pump 2: CNTEST-pin 1 and CNTEST-pin 5 (GND)
12.
Replace the safety/slide clamp assembly when it cannot be calibrated
(“Replacement of Safety/Slide Clamp Assembly” on page 8-19).
13.
Apply a thin film of Red Glpt to VR802 to lock it in position.
14.
