Troubleshooting
1. The Drive will not operate on the internal battery power source.
A. Verify that the
Power Source Selection Switch (B),
is in the
BATTERY
position.
B. Verify that the
Mode of Operation Selection Switch (C),
is in the
RUN
position.
C. Verify that the pump head, tubing size and formulation are correct and
recommended for this drive.
D. If using a PTFE pump head, install and start the tubing per the instructions
in the pump head manual. Excessive tightening of the occlusion bed can
jam the drive mechanism. Tighten the occlusion bed gradually as indicated
in the pump head manual.
E. Verify that the
Pump Rotational Selection On/Off Switch (H),
is either in the
CW
or
CCW
position for the desired rotation. The
Power
indicator in the
Drive Controls section will be illuminated.
F. Toggle or activate the
Battery Status Indicator (F).
If the indicator is RED,
recharge the battery immediately. You have drained or exhausted the
available power of the internal battery.
G. If the
Battery Status Indicator (F)
does not illuminate, remove the control
panel and check for loose connections to the battery.
H. Use a digital multi-meter (DMM) set to DC volts to check the battery
potential. If below 9 volts DC, replace battery.
I. If none of the above solutions work, contact your authorized dealer for
service.
2. The Drive will not run using external power supplied by the AC/DC Power
Supply/Converter.
A. Verify that the
Power Source Selection Switch (B),
is in the
EXTERNAL
position.
B. Verify that the
Mode of Operation Selection Switch (C),
is in the
RUN
position.
C. Verify that the pump head, tubing size and formulation are correct and
recommended for this drive.
D. If using a PTFE pump head, install and start the tubing per the instructions
in the pump head manual. Excessive tightening of the occlusion bed can
jam the drive mechanism. Tighten the occlusion bed gradually as indicated
in the pump head manual.
