Section 5 Pump Maintenance & Repair
Note
Parts for Configuration 1 and Configuration 2 are not interchangeable.
5.10 Troubleshooting The following sections contain tables listing the most commonly
used test points and their voltages. Refer to the controller schematic
and the pump schematic (available online on our Web site).
DANGER
RISK OF ELECTRIC SHOCK -
DISCONNECT THE ELECTRIC POWER BEFORE
SERVICING. ONLY TRAINED SERVICE
PERSONNEL MAY REMOVE THE CASE TOP.
DANGER
RISQUE DE CHOC ÉLECTRIQUE.
COUPER L´ALIMENTATION AVANT LA
RÉPARATION. L´USAGER NE DOIT PAS
DÉMONTER L´INSTRUMENT OU DÉRANGER LE
MÉCANISME DEDANS. ADRESSER LA
REPARATION SEULEMENT AUX TECHNICIENS
COMPÉTENTS.
5.10.1 Power Supply (A1) Output voltages of the power supply can be verified. The voltages
in the pump unit, between circuit common (TP106) and the fuses
or at the test points should be:
F104 22 VDC to 31 VDC
F103 8.1 VDC to 13 VDC
F102 22 VDC to 31 VDC
TP111 15 VDC 0.6 VDC
TP110 15 VDC 0.6 VDC
TP109 5 VDC 0.3 VDC
The voltage between motor common (TP101) and +VM (TP105)
should be + 30 V to + 45 V (low speed) or +60 to +90 V (high
speed). See section 4.
5.10.2 Controller The voltages in the controller unit between circuit common
(TP134) and the test points should be:
TP106 5 VDC 0.002 VDC
TP112 8.1 VDC to +13 VDC
TP131 15 VDC 0.6 VDC
TP135 15 VDC 0.6 VDC
TP136 10 VDC to +12 VDC
TP137 10 VDC to -12 VDC
