6. SPECIAL FUNCTIONS
POWER START
With the power start setting, the engine will start (when stopped first) at full power when any speed button is
pressed. The motor rotates at full speed for approximately 15 seconds and then returns to its pre-set speed. This
makes it easier to get the motor started if the motor has been partially frozen in cold weather when it is stopped.
Note! The power starter may not be able to start a badly frozen engine. If it is detected that the engine does not
start, the frozen engine should always be thawed according to the manufacturer’s instructions (e.g. by blowing
warm air into the removal hose) and not attempted by forced start, as this could break the engine.
FIRST-SPEED ADJUSTMENT
If desired, a value different from the factory setting (retrievable from the memory bank) can be set for the first
speed, e.g. to make the housing 24/7 more suitable for basic ventilation. For adjustment, the hood must be
switched on and the motor switched off. The T4 key is held down for about 7 seconds, after which the T1 lights
up and the desired control voltage can be set to the first speed. The voltage value of the memory bank is thus
overwritten with the new voltage value.
The value of one speed can be adjusted for EC motors between approx. 3.0 - 10.0 VDC, in half-volt incre-
ments. For the AC motor, the adjustment range is approx. 100 - 230 VAC.
The voltage value is indicated by the LEDs so that T4 flashes first the integer and then the decimal (this only if
the voltage is not an integer).
e.g.:
We assume that the EC motor is sometimes set to a single speed of 3.5 VDC.
•
S1 does not light up at first, this means that next flashing T4 multiplies the total part of the voltage (i.e. 3)
•
The LED T4 flashes 3 times
• After this, S1 lights up and remains lit.
•
The LED T4 flashes 5 times
E.G. the flashing cycle continues until the settings are exited.
CHANGING, SAVING AND EXITING ONE-SPEED CONTROL VOLTAGE
Go to set-up mode first, if you weren’t already there. See Section 6, “Adjusting the first speed”
• Increasing the control voltage. Press the T4 key quickly and release it. Voltage setting increases by 0.5 VDC
(EC) or approx. 10-15 VAC (AC, trms) with each press
• Reducing the control voltage. Press the T3 key quickly and release it. Voltage setting decreases by 0.5 VDC
(EC) or approx. 10-15 VAC trms (AC, trms) with each click
•
If the minimum or maximum limit of the voltage control range is reached, T2 flashes four times
• After each voltage setting change, wait approximately one second until the keys respond again to new press-
es.
•
To save the current settings (just made) and exit the menu, lightly press the L key (= lights). LED lights T1,
T2, T3 and T4 flash three times. The settings are now saved.
• If you want to exit the settings without saving the new voltage value, lightly press the T1 key. LED lights T1,
T2, T3 and T4 flash once. Settings were not changed
FACTORY RESETTINGS
•
First go to setup mode (see above). Lightly press the T2 key. LED lights T1, T2, T3 and T4 flash six times to
confirm. The factory control voltage value according to the memory bank has now been restored to the first
speed (M.B. #1).
POTENTIAL FREE RELAY HEAD INFORMATION
The cooker hood provides potential - free relay tip information (max. 5A). This can be used for example. for
the control of the ventilator, in compensation for subpressure. The relay tips close when the motor is on (any
speed). The tips are open when the motor is not running. See separate installation instructions for connection.
7. REMOTE CONTROL
This appliance may be controlled using a remote
control.
