6 - MAINTENANCE
• All work relating to installation, commissioning
and maintenance must be carried out by
experienced and qualified personnel.
• Do not carry out any work before the VARMECA - 10
power supply circuit has been cut off and locked, and
wait 2 minutes for the capacitors to discharge.
6.1 - Servicing
No specific servicing is required for VARMECA - 10 motors,
apart from the regular removal of dust from the ventilation
louvres and the cooling fins located at the bottom of the box.
Do not dismantle the VARMECA - 10 while it is still under
guarantee, as this would then immediately become null
and void.
CAUTION :
The rear cover protects the electronic boards and should
only be removed for adjustment using the mini DIP
switches marked K1, K2, K4 (0.25 to 2.2 kW and 5.5 and
7.5 kW ratings)
✶
.
Certain components which are sensitive to electrostatic
discharges may be destroyed simply by touching them.
Do not leave any metal object in the connection area, as
this could cause a short-circuit.
✶
For 3kW and 4kW ratings, K1, K2 and K4 can be accessed
without removing the rear cover, via the connection space,
through a special opening in the rear cover, protected by a
plastic plug.
6.2 - Measurements
6.2.1 - General
The input voltages can be measured using ordinary
instruments.
The motor current is not measured on the VARMECA - 10
power supply (L1, L2, L3). It is measured using an ordinary
clamp ammeter on the longest wire, which forms a loop on the
side of the connection circuit.
6.2.2 - Procedure for measuring the motor
current (if the motor wire loop is inaccessible)
- Open the VARMECA - 10 power supply circuit and
lock it.
- Wait 2 minutes for the capacitors to discharge.
- Open the cover of the VARMECA - 10.
- Remove the mains cable (L1, L2, L3).
- Remove the 3 TORX 20 + slot type screws from the
connection circuit.
- Pass the longest motor wire along the side of the
connection circuit.
- Replace the connection circuit and fasten it.
- Reconnect the mains (L1, L2, L3).
- Pass the clamp ammeter through the motor wire
loop.
