REMKO VRS
■ Y / Δ - starting
The measured rated current
must not exceed the value
shown on the motor rating
plate.
thermal overcurrent relay
The function of the overcurrent
relay or its setting can be checked
by removing a fuse.
A correctly operating relay must
operate after about 30 seconds.
Excessive current
consumption
If the fan motor should consume
excessive current despite correct
electrical connection and sufficient
system voltage, under no circum-
stances must the overcurrent relay
be set higher or overridden.
In this case, the air-sided resist-
ances (inlet/outlet side) must be
checked for correct dimensioning.
Suitable measures must be pro-
vided for this purpose.
Commissioning
Commissioning
Commissioning of the unit and the
forced-air burner must take place
by the manufacturer or a specialist
authorised by the same. All regu-
lating, control and safety devices
must be checked for their proper
functioning and correct adjust-
ment.
■ The commissioning of oil and
gas-fired heating appliances
must always be carried out by
authorised specialists.
■ All bolts and nuts of the fan
and burner mounts must be
checked for tightness.
■ All air outlet grilles must
be opened and adjusted if
necessary.
■ The settings and function of
the triple function combination
controller must be checked.
■ Switch on the local main switch
or fuses.
■ Set the room thermostat
higher than the existing room
temperature.
■ Open the fuel supply and
switch the switch to the „Heat“
position.
Factory supplied oil burners
start with a delay due to the
standard oil preheating (up to
VRS 50)!
■ The fuel oil or gas flow rate
must be adjusted appropriate to
the heat load of the appliance.
See appliance rating plate!
Commissioning of fan motor
Testing drive
1. The mounting screws of the
complete drive must be checked
for tightness.
2. The initial tension of the drive
belt(s) must be checked.
Current consumption
measurement
1. To prevent incorrect measure-
ments, the grilles in the air
duct or air outlet hood must be
opened.
All supplied air inlet and metal
panels must be mounted on the
appliance.
2. Check the system voltage for
correctness.
3. Carry out the necessary meas-
urements and adjust settings as
required.
■ Direct starting
The measured rated current
must not exceed the value
shown on the motor rating
plate.
Check the thermal overcurrent
relay appropriate to the rated
current of the drive motor and
adjust if necessary.
NOtE
In order to exclude measure-
ment errors, each phase should
be measured separately.
AttENtION
The thermal overcurrent relay
must only be operated in a
manual mode.
Under no circumstances must
the relay switch on again
automatically
AttENtION
The fan must be checked for
correct direction of rotation.
NOtE
The rated current of the drive
motor must be multiplied by
the factor 0.58.
Check the setting of the
thermal overcurrent relay with
respect to the calculated value
and correct if necessary.
