The electrical control panel is composed of a power supply (switching power supply, load electronics and lead accumulator

system) as well as of the devices central ventilation module, central relay module and ventilation group module. The control

panel is provided with up to three switching power supplies (unit sizes with ED 30%) depending on the particular version. The

accumulator capacity is based upon output (24 V DC, ripple < 500 mV, ripple < 5 %) and internal consumption of the control

panel.

( ) This current applies to the complete system in continuous operation.

( ) This range of tolerance applies to the adjusted nominal output voltage and to the defined short time current.

The overload detection is provided by an electronic fuse in the SNT

Note! It is not permitted to exceed the

max. total current (e. g. at the power

supply, EV-72=72 A). This would lead

to an automatic regulation by the

switching power supply, SNT (that

means emergency current mode).

The switching power supply, type SNT-120 serves as the main power source and also is responsible for the mains supply of the

control panel. SNT is resistant against permanent short circuit and permanent no-load operation. Cooling occurs exlusively in

a natural way by some louvers at the housing

The mains supply for the switching power

supply has to lie within the nominal voltage

range of 195 - 265 V AC

The mains fuse protection by the customer

occurs with 16 A (fuse characteristic C or

more delayed).

The mains connection cable cross section

must be at least 0,75 mm² for each switching

power supply

Every switching power supply is provided with a monitoring output. This signals a fault in

following cases:

- mains failure (undervoltage detection U < 195 V AC)

- short-circuit resp. overload at the SNT-output

- technical defect of the SNT

- inactivity of the SNT (no energy output possible)

In case of failure the emergency current mode of the system gets triggered by the control

electronics.

Output currents from 24 A can be

realized when connecting several

switching power supplies in parallel

(max. 3 = 72 A).

supply

Lead accu, 12V

Load electronics, LB-1*0

The emergency current mode of the power supply, EV-** is provided by two 12 V lead accus, that are connected in cascade.

The needed capacity is defined by the individual discharging phase. Charging the lead accu is accomplished in the form of an

I/U-charge by an DC/DC-converter. That means that the charging current in the first charging cycle is limited to a constant

charge current. When the accu voltage reaches the charging end voltage, this voltage is limited by regulating the charge

current.

The closed current specified in the table

(e. g. for additional relais) may not be

exceeded. In case of emergency current

mode (max 72 h) the needed power for

operating the actuators (2 x open and 1 x

close within 3 minutes) is thereby

provided.

Measurement readings control electronics

Charge

If no charging current is indicated during

the measurement, after approx. 40

seconds a second measurement has to

be accomplished. The reason therefor is,

that after a charging cycle (8 minutes) a

break- and measure period (approx. 40

seconds) is required for the automatic

accu monitoring.

For example a non-connected

accumulator gets detected and

consequently a fault alarm is indicated.

The LED indication “O.K.” at the charging

electronics blinks (= fault). If the lead accu

is defective, this also is signaled by a fault

alarm.

During mains operation the emergency accu is permanently charged with an I/U-charging. In emergency current mode the

charging gets disconnected. After discharging the load electronics is able to charge 80 % of the nominal capacity within 24 h

and after another 48 h it charges the accu 100%. According to VdS 2593 resp. EN 12101-10 the charging is dependent on

temperature. Thereby the charging voltage is adjusted according to the environmental temperature.

The temperature-operated charging voltage must be within the range of

26,7 V and 28,2 V (e. g. at an environmental temperature of 20° C the

charging voltage is at approx. 27,5 V). This reading can be measured at a

charged accu (without disconnecting the accu from the charging).

In order to check the function of the

charging at a discharged accumulator

anyway, the charging current must be

measured. The reading is approx. 1,5 A.

Ventilation control panel (connection +24)

The output +24 is required for the ventilation function of the electrical control panel. That means that all relevant ventilation

functions (e. g. wind/rain detector) are provided with power via that output.

Measurement readings control electronics

All three status outputs of the power supply, EV-** (+24, H, D) are provided with an overload detection. That means, if the

current exceeds a defined measurement at one of these outputs this particular output gets disconnected. After the

disconnection the control electronics proves whether there is still an overload or not. During this overload phase this fault state

is indicated as a fault indication.

Charging device, mains failure and undervoltage (connection H)

The output H provides a status signal (OK / fault). This output is active in the normal mode (no fault). If the power supply, EV-**

goes into failure mode this signal gets relayed to the electrical control panel via the output H.

( ) The extended fault indication time results

from the cycle time of the accu monitoring.

Total discharge protection (connection D)

In the emergency current mode the output D is responsible for giving a signal to the electrical control unit when the total

discharging state of the accumulator is reached. Only in emergency current mode this output will cause a fault indication.

During mains operation this already will be indicated via the fault indication output H when reaching the charging end voltage of

the accu.

Disconnect the output wire from the power

supply, EV-**. Afterwards the switching

power supply has to be gradually increased

again immediately (LED-indication at SNT-

120). If the accu fuse is defective the LED

O.K. at the control electronics will start to

blink. => replace the accu fuses. Control the

short circuit source before connecting the

EV-** to the SHEV system.

Check the glass fuse (3,15 A) at the control

electronics, LB-1*0. If that is defective,

replace it by a new fuse (enclosed at the

EV-**).
