Mounting; Electrical Connection - Remak DoorMaster C1 Installation And Operating Instructions Manual

Wiring and Commissioning
As standard, the DoorMaster COMFORT air curtains
are designed to be controlled by remote (external) con-
trollers; therefore, no controls are situated on the air
curtain casing. For the number of speed and heating
stages, and control features, refer to table 9, page 21.
External controllers (switches) must be dimensioned at
least for the minimum inductive load; for values of in-
ductive load, refer to the applicable tables further in the
respective tables on pages 12-13.
Figure 14 – WAGO terminals
The selected controller must enable device switching
off. For types of connecting cables for corresponding
controllers, refer to page 21. WAGO screw-free termi-
nals are used to connect the conductors. If stranded
conductors are used, it is recommended to provide their
insinuated ends with cable tubes.
Electric Heater Protection Elements (E1
and E2 versions)
Two thermal protections are connected in series with
the air curtain control circuit to prevent the heating coil
battery overheating; their status is evaluated by a re-
lay. If the thermal protection circuit is open, the control
signal will be interrupted, and thus the heating element
power supply will be disconnected.
The air temperature of the electrical air curtain is set to
45°C (maximum permissible temperature setting).
The setting can be performed by means of the cont-
rol thermostat (TH 167) situated inside the air curtain,
which allows downward temperature correction.
Wiring Procedure
Open the inlet panel and remove it.

Remove the right side electrical equipment cover

(C1), respectively the lower service panel (D2 air cur-
tain).
Connect the controls and control elements as fo-

llows:
a) Fan Connection
If air curtain control is not considered, connect the
switch to the LV+Q3 terminals. If air curtain control is
used, connect the switch to the LV+Q1+Q2+Q3 termi-
nals.

Note: There is no possibility to control the speed with
the C1 air curtain basic version (without TR).
b) Electric Heater Connection
The heating rods are Y-connected to 3+N+PE 400V AC
50 Hz power supply system. Connect the electric heater
to the LE+Q1E(+Q2E+Q3E) terminals.
c) Door Contact Connection
If the door contact is used, connect it to the DK1:DK2
terminals. These terminals are interconnected with a
jumper in the factory - remove this jumper.
d) Electric Heater Protection Connection
The power supply of air curtains equipped with an elect-
ric heater (E1 and E2 versions) must be pre-protected
with an under-voltage circuit breaker which must be
connected to the emergency circuit terminals (TK, TK)
in accordance with the corresponding wiring diagram on
page 17 and the following pages.
e) Main Power Supply Line
With air curtains equipped with an electric heater (E1
and E2 versions), connect the main power supply line
to the X1: L1+L2+L3+N+PE terminals; with air curtains
equipped with a water heater (W and N versions), co-
nnect the main power supply line to the X1: L1+N+PE
terminals. Install and properly fix the removed parts in
reverse order.
Commissioning
Before the first start-up, perform the following:
Check the air curtain mounting.

Check the connection valves' openings and whether

the water heat exchanger is filled with water - check the
water heat exchanger and its connections for leakages.
Check the shut-off valves for functionality.

Check the electrical connections for completeness
according to the corresponding wiring diagram, the
screw connections for tightness and proper connection
of the media feed lines.
Check the air inlet and outlet areas for obstructions.

Switch on the power supply.

Check the switching of the fan, respectively electric
heater output stages.
Check the proper directing of the outlet slit.

Start the air curtain, and monitor its operation
for 30 minutes.
Ensure the initial inspection of electrical equipment

is performed.
Attention!
Installation and operation of the air curtain without

the lockable main switch enabling safe power supply
disconnection is forbidden.
It is forbidden to start the air curtain without pro-

tective guard covers. An "ATTENTION! ELECTRICAL
EQUIPMENT!" label indicates the electrical accident
hazard. All the covers must be properly secured during
operation.
Any tampering with the air curtain protection circuits,

or modification of their parameters (emergency thermo-
