8. Commissioning
8.1 Filling and venting the system
CAUTION! Danger of damage to the pump!
The pump must not be allowed to run dry.
The system must be checked prior to switching
on the pump.
8.1.1 Venting – inlet mode (Fig. 1)
- Close the two stop valves (1 + 2).
- Loosen the venting screw (4).
- Slowly open the stop valve (1) on the suction
side.
- Close the drain cock as soon as the air has been
emitted and fluid runs out of the pump (4).
WARNING! Risk of burns!
If the fluid is hot and the pressure is high, there
is the danger of scalding or other injuries being
caused by the stream ejected from the drain
cock.
- Fully open the stop valve (1) on the suction side.
- Open the stop valve (2) on the pressure side.
8.2 Commissioning
CAUTION! Danger of material damage!
The pump must not be allowed to run at zero
volume flow (stop valve closed on the pressure
side).
The following flow rate must be ensured:
Pump type Min. volume
flow
MVISE 2 0.4 m³/h
MVISE 4 0.5 m³/h
MVISE 8 1 m³/h
WARNING! Danger of injury!
Depending on the pump's or system's operat-
ing conditions (fluid temperature, volume flow),
the entire pump, including the motor, can get
exceedingly hot. Risk of burns if the pump is
touched!
CAUTION! Check the direction of rotation!
Incorrect direction of rotation causes poor pump
output and the possible overloading of the
motor.
- In the terminal box there is a control lamp
(Fig. 1, pos. 9), which illuminates if the direction
of rotation is correct.
- If the control lamp does not illuminate, there is
no supply of operating voltage or the direction
of rotation is incorrect. In the last case, swap
the two phases of the mains connection.

8.3 Operation of the converter

8.3.1 Control elements

The converter is controlled using the following
control elements:
Rotary knob
• Selecting a new parameter only requires rotating
the knob in direction "+" to the right or "-" to
the left.
• A short impulse on the rotary knob confirms this
new setting.
DIP switches
This converter has a block of five DIP switches
(Fig. 4, pos. S) each with two positions.
ON
1 2 3 4 5
• DIP switch 1 switches from "OPERATION"
mode [DIP switch 1 OFF] to "SERVICE" mode
[DIP switch 1 ON] and back again. The
"OPERATION" position authorises the opera-
tion of the chosen mode and stops access to
the parameterisation (normal operation). The
"SERVICE" position allows the user to carry out
parameterisation of the different operations.
• DIP switch 2 is used to activate or deactivate the
"Access lock" (see section 8.3.6.5).
• DIP switches 3 and 4 must be kept in the
ON position.
• DIP switch 5 is not used and must be kept in the
OFF position.
Relay
