Trouble Shooting:
1.
Motor starter cuts out pressure/vacuum pump:
1.1 Check that incoming voltage and frequency corresponds with the motor data plate.
1.2 Check the connections on the motor terminal block.
1.3 Incorrect setting on the motor starter.
1.4 Motor starter trips too fast.
Solution: Use a motor starter with a time delay trip (version as per IEC 947-4).
1.5 Filter cartridges of exhaust filter are contaminated.
1.6 The regulating valves are dirty, so allowing the limited pressure or vacuum point to be exceeded.
2.
Insufficient suction or pressure capacity:
2.1 Inlet and/or exhaust filters are contaminated.
2.2 Suction pipe work is too long or too small.
2.3 Leaks on pump or on the system.
2.4 Blades are damaged.
3.
Pressure/vacuum pump operates at an abnormally high temperature:
3.1 Ambient or suction temperature too high.
3.2 Cooling air flow is restricted.
3.3 Problem as per 1.5 and 1.6.
4.
Unit emits abnormal noise:
4.1 The pump cylinder is worn. Solution: send your complete unit off for repair to the supplier or approved service agent.
4.2 The regulating valve is noisy. Solution: replace valve.
4.3 Blades are damaged.
Appendix:
Repair on Site: For all repairs on site an electrician must disconnect the motor so that an accidental start of the unit cannot happen.
All engineers are recommended to consult the original manufacturer or one of the subsidiaries, agents or service agents. The address of the nearest
repair workshop can be obtained from the manufacturer on application.
After a repair or before re-installation follow the instructions as shown under the headings “Installation and Initial Operation”.
Lifting and Transport: To lift and transport the TR 81 DVV the eye bolt on
the pump must be used.
The weight of the pumps are shown in the accompanying table.
Storage: TR...DVV units must be stored in dry ambient conditions with
normal humidity. We recommend for a relative humidity of over 80% that
the pump unit should be stored in a closed container with the appropriate
drying agents.
Disposal: The wearing items (as listed in the spare parts lists) should be
disposed of with due regard to health and safety regulations.
