1Concept of Control Centre
● SHEVS Control Centre with four outputs for connecting 24 V actuators (RWZ 5f-xx) or 48 V actuators
(RWZ 5f-xx-48V)
● Functions according to EN 12101-10 (power supply), ISO 21927-9 (control), VdS 2581 and VdS 2593
● Selectable group configuration: one or two SHE groups, up to four ventilation groups
● For every SHE group, two signal lines:
− Line T: Automatic fire detectors or fire alarm control panel (FACP)
− Line t: Manual call points RT 2 or RT 4 (main alarm point RT 2/4-*-BS or secondary alarm point
RT 2/4-*). Connectable versions see section 6 “Technical Data”
● Line Y for connecting a FACP (activating the alarm in both SHE groups)
● Reset the alarm / the detectors using the button in the main alarm point or in the Control Centre
● Selectable functions:
− “Auto Close” (automatic closure after resetting an alarm)
− “Fault = Alarm” (fault in a signal line will trigger an alarm)
− “Automatic OFF” (automatic travel commands - apart from the alarm - are disabled)
− “Thermal Alarm” (alarm on exceeding an enclosure inside temperature of 70 °C)
− “2-detector-dependency” (2-detector dependency for automatic fire detector in line T)
− “WRC” (automatic closure in the case of active wind and rain control)
● Possibility of connecting ventilation button for each ventilation group, also with indication of position A
● For each actuator output adjustable ventilation position h and ventilation time D
● Possibility of connecting an external wind and rain control, e.g., type WRS. Internal wind and rain control, op-
tional
● Internal service display for indicating the detailed status
● The use of K + G / Grasl actuators is recommended. When controlling 3rd party actuators, compatibility is to
be checked. Also note section 6 „Technical Data“ for this
● Connectable actuators: 24 V / 48 V actuators, travelling time for full stroke at rated load (total travelling time)
< 4 minutes
● When directly changing the sense of travel, the actuators are stopped briefly before change of sense
● Sheet steel enclosure, light grey (RAL 7035)
1.1 Options / Accessories
● PK: Potential-free contacts (PFC) for alarm and/or fault forwarding
● PK-SA: Potential-free contacts for forwarding indication of position
● WTM: Outputs for controlling external warning devices in case of alarm or fault
● WRM: Internal wind and rain control. Connection of wind sensor WM and/or rain sensor RS is required (ac-
cessory)
iThe PK-SA and WTM options cannot be provided at the same time!
2Putting into service / Putting out of service
Work may be performed only by qualified personnel!
Before starting any work, it is mandatory to deflect static charge!
We do not assume any guarantee or liability for defects caused by faulty connection.
i
Planning and design of SHEVS require observation of the following rules, as far as applicable: National build-
ing codes/model building code and regulations of local building and fire safety authorities, VDE regulations
(particularly VDE 0100, 0108 and 0833), VdS Guidelines 2098 and 2221, DIN 18232, EN 12101, DIN 4102,
model line systems policy.
2.1 Installation / Putting into service
! Perform work only in de-energised condition!
!Actuators must not be actuated directly (e.g., with external accumulators during installation / maintenance)
when they are already connected. This can lead to defects in the power output.
● Fasten the enclosure securely to a wall using suitable mounting material. Guide the connection cables
through the openings provided and wire them according to the connection diagrams.
● Make function settings (see 3.2).

SHEVS Control Centre RWZ 5 f
4
● Turn on line voltage. The indicators and the service display light up briefly. Subsequently, the indicator s
flickers for about 15 s (calibration process). If the indicator s is permanently lit, there is a fault in a signal line
(see 5).
● Insert the accumulators in the enclosure as illustrated on the “Line voltage, Installation, Accumulators” plan
and connect them.
● The indicator o lights up, the indicator s goes out, the system is ready for operation. If a fault is still dis-
played, follow the instructions in section 5 “Detection of fault / Troubleshooting”. If necessary, decommission
the Control Centre again (see 2.2).
● While putting into service, check all functions and indicators of the Control Centre and its components. The
individual functions are described in section 3. Also simulate faults and check detection (see 5).
● To finish putting into service, retract all actuators completely (press button z).
iAfter about 24 hours of continuous operation without mains failure, the accumulators are sufficiently charged
to achieve the full standby time in case of mains failure.
2.2 Putting out of service
● Disconnect the accumulators from the Control Centre (remove accumulator connection line or fuses F2.1 and
F2.2).
iCharged accumulators have a shelf-life of about 6 months. They must be recharged if stored for a longer
period.
● Switch off line voltage.
3Functions and operation

● “Thermal Alarm” DIP switch S1-4:
In the ON position, the alarm function (see 3.4) is executed when the inside temperature of the enclosure ex-
ceeds 70 °C. Factory setting: OFF (no alarm when 70 °C is exceeded).
● DIP switches S1-5 and S1-6: Do not change setting. Factory setting: OFF.
● “Fault = Alarm” DIP switches S2-1 (SHE group 1) and S2-2 (SHE group 2):
In the ON position, the alarm function (see 3.4) is executed if a signal line is faulty. The alarm can also be re-
set by pressing the button Reset r in a main alarm point or the Control Centre before eliminating the fault. If
a switch is in ON position, then the function is also activated in line Y.
Factory setting: OFF (no alarm in case of fault).
● “2-detector-dependency” DIP switch S2-3 (SHE group 1) and S2-4 (SHE group 2):
In the ON position, two automatic fire detectors must have responded in line T before the alarm function
(see 3.4) is executed.
As soon as the first automatic detector has responded, the pre-alarm is activated: The indicators r on the
logic board and the manual call points flash, manual call points with buzzer S emit an intermittent warning
tone. After changing the switch position, a recalibration is performed automatically (see 2.1).
Factory setting: OFF (no 2-detector-dependency in line T).
!When the function is activated, note the changed terminating resistor (see connection diagram).
● “Automatic OFF” DIP switch S3-1 (ventilation group 1) to S3-4 (ventilation group 4):
In the ON position, the following automatic functions are disabled: Auto close, ventilation position and ventila-
tion time, repetition of cycle z and closing in case of mains failure or active wind and rain control. Actuators
operate during ventilator operation only if a button a / z is pressed. The indication of position is deactivated.
Factory setting: OFF (automatic enabled).
iWhen changing from position ON to OFF, the actuators are automatically retracted. Ventilation can be re-
sumed only after 4 minutes.
● “Auto Close” DIP switches S4-1 (actuator output 1) to S4-4 (actuator output 4):
In the ON position, the actuators are automatically retracted after resetting an alarm. When the function re-
sponds, ventilation can be resumed only after 4 minutes.
Factory setting: ON (automatic closure is activated).
● “WRC” DIP switch S5-1 (actuator output 1) to S5-4 (actuator output 4):
In the ON position, the actuators are automatically retracted if a wind and rain control is activated.
Factory setting: ON (automatic closure in the case of active wind and rain control).
iIn the OFF position, the respective output can be actuated by the corresponding ventilation button even
when the WRC is active.

3.3 Indicators / functions of the manual call points
● For activation and reset, see 3.4.
● Indicators:
− r (red, RT 2/4-*): Alarm, see 3.4.
− o (green, RT 2/4-*-BS): Trouble-free operation. Goes out when a fault is detected.
− s (yellow, RT 2/4-*-BS): Fault, see 5.
● Button Reset r (RT 2/4-*-BS):
Reset the alarm function (accessible after opening the door with a key).
● Manual call point with buzzer S for alarm and fault signal (RT 2/4-*-BS-AA):
The buzzer emits a continuous tone in the event of alarm, and an intermittent warning tone in the event of
pre-alarm or fault. The warning tone is switched off by pressing the button Reset S.
3.4 Alarm functions
During the execution of an alarm function the ventilation functions are disabled.
iWhen configuring 2 SHE groups (see 3.2), the following description applies accordingly to the second group.
● Alarm function: Upon detecting an alarm, the actuators of the SHE group are fully extended. The indicator
r lights up and manual call points with buzzer S emit a continuous tone. Repetition of cycle a is executed for
30 minutes (extend, briefly retract, extend again).
● Resetting the alarm function: Resetting is done by briefly pressing the button Reset r in a main alarm
point or the Control Centre. Then the indicators r will go out and the buzzers S will be switched off.
iIf the actuators are retracted by pressing the button zafter an alarm has been reset, ventilation can be
resumed only after 4 minutes.
● Manual call points: For manual alarm signalling, break open the glass of the manual call point and press the
control button until the indicator r confirms the detection of the alarm.
For maintenance work, the door of the manual call point can be opened with a key.
● Automatic fire detectors: The alarm is triggered automatically (depending on the type of detector due to
smoke and/or heat detection).
If an automatic fire detector responds immediately after resetting, press the button Reset r again (smoke
particles may still be present in the detector).
● Fire Alarm Control Panel (FACP): When an alarm is signalled by the FACP, the alarm function will be exe-
cuted in both SHE groups. The alarm is reset at the FACP.
iOther alarm functions (“Fault = Alarm”, “Thermal Alarm”, “2-detector-dependency”, “Auto Close”) see 3.2.
3.5 Ventilation functions
iConfiguration of ventilation groups: see 3.2.
iThe ventilation position, the ventilation time and the wind and rain control are disabled as long as the function
“Automatic OFF” is enabled (see 3.2). Actuators operate only if a button a / zis pressed.
!When performing ventilation functions, do not exceed the duty cycle of the actuators.
3.5.1 Manual ventilation
● After briefly pressing a ventilation button (a / z), the actuators of the ventilation group travel up to the end po-
sition or the set ventilation position h (see 3.5.2). Pressing it again stops the actuators. By pressing the but-
ton for the reverse direction of travel, the travelling direction is reversed after a brief stop.
● When pressed longer (> 1 s), the actuators travel as long as the button remains pressed. It is also possible to
travel up to the end position or up to the set ventilation position.
3.5.2 Setting the ventilation position h
iThis setting can only be made when the system has no faults and WRC is not active.
Initially, all actuators must be completely retracted and the travel command zhas to have finished.
● Set the travelling times towards OPEN and CLOSED to define the desired ventilation position.
Factory setting: 15 s travelling time OPEN, 30 s travelling time CLOSE.
The ventilation position can be enabled / disabled for each actuator output:

SHEVS Control Centre RWZ 5 f

− Enabling / disabling the ventilation position: Press button h for longer than 3 s. The display briefly shows
1(enabled) or 0 (disabled).
− Reset to factory setting: Press button h for longer than 6 s. The display briefly shows ?.
● The travelling times can be set for each actuator output or for each ventilation group.
o Setting the travelling times for each actuator output (ox):
− Briefly press the button h to enter programming mode for the respective actuator output
(display: ox)
− Briefly press button h to extend the actuators. When the desired ventilation position is reached,
press the button h again.
− Briefly press button h to retract the actuators. When all actuators are completely retracted, press the
button h again. The indicator ox goes out.
− The actuators automatically travel to the ventilation position for verification and then retract again.
o Setting the travelling times for each ventilation group (Lx):
− Briefly press the button h to enter programming mode for the respective ventilation group
(display: ox) and then press the associated button D (display: Lx). The indicator A flashes in the
ventilation buttons of the group.
− Briefly press a ventilation button a to extend the actuators. When the desired ventilation position is
reached, press the ventilation button a again.
− Briefly press a ventilation button z to retract the actuators. When all actuators are completely re-
tracted, press the ventilation button z again. The display Lx goes out.
− The actuators automatically travel to the ventilation position for verification and then retract again.
iIf a changeover contact is used for ventilation, then the ventilation position can only be set for each actua-
tor output.
i If an indicator aflickers when activating the programming mode, then the actuators of the related output
are not fully retracted and the ventilation position cannot be set. By pressing the button h, closing can be
activated for these outputs (display: üx).
iThe programming mode is cancelled automatically after 15 minutes without button activity or manually by
double clicking on the button Reset S.
3.5.3 Setting the ventilation time D
● The ventilation time can be set for each actuator output in 5-minute steps (5 to 30 minutes) using button D.
The first press displays the set value, pressing again changes the value. After the set time has elapsed, the
actuators retract automatically. With setting 0 the ventilation time is deactivated (= factory setting).
3.5.4 Indication of position A in the ventilation button
● The indicator
− lights up: Actuators are in OPEN position
− flickers: A travel command is active
− blinks: Ventilation function is blocked (also see the indicator in the device)
− flashes: Ventilation position can be set with this button (see 3.5.2)
In case of a travel command towards CLOSED, the indicator goes out latest after 4 minutes
iIn case of a mains failure or if the function “Automatic OFF” is enabled (see 3.2), the indicator is disabled.
3.5.5 External Wind and Rain Control (WRC)
● If the wind and rain control is active, the actuators are retracted automatically. The ventilation functions are
disabled. The indicator w on the logic board lights up, until the WRC releases the ventilation functions once
again. An alarm has priority.
i
Note the setting of the “WRC” function (see 3.2).
3.6 Repetition of cycle z
● If not all actuators are properly retracted (e.g., actuator has switched off due to a gust of wind), the repetition
of cycle function can be activated by briefly pressing the ventilation button z. The actuators are briefly ex-
tended and following the closing command is executed once again.
i
Note the setting of the function “Automatic OFF” (see 3.2).

SHEVS Control Centre RWZ 5 f

3.7 Mains failure
● In case of mains failure, the accumulators cannot be charged, but they provide the operating power for the
standby time. Actuators in ventilation position are retracted and pressing the ventilation button a is ignored.
Alarm functions are not affected by the mains failure.
The mains failure must be rectified immediately to prevent the deep-discharge protection from responding, to
recharge the accumulators, and to ensure safe functioning of the system.
i
Note the setting of the function “Automatic OFF” (see 3.2).
● Deep discharge protection: If the accumulators are in critical condition, the device is switched off com-
pletely. However, a low quiescent current continues to flow (in addition to the natural self-discharge). There-
fore, without recharging, there is a risk of permanent damage to the accumulators after only a few days.
4Maintenance
● In the course of maintenance - unless other local regulations apply - check all the functions and displays of
the device and the components at least once a year. This also includes checking the terminal points, connec-
tion cables, indicators and fuses, and cleaning of various components, if necessary.
The individual functions are described in section 3. Likewise simulate faults of the signal lines and power sup-
ply and check the detection (see 5).
● Maintenance due indication
If the maintenance company has enabled this function, the indicator 9 flashes after about 11 months of ser-
vice life. After about 14 months, the overdue maintenance leads to the indication of a fault s.
● Accumulators:
− Check the accumulators at least once a year for proper functioning. They should be replaced following a
typical service life of 3, but no more than 4 years in an ambient temperature of 20 °C. For every 10 °C rise
in ambient temperature, the service life decreases by about 1 year!
− Checking the accumulators:
Press the button Test r (test alarm is executed in accumulator mode) and completely extend the actua-
tors. If the accumulator voltage drops too low during this, the accumulators are defective. A fault will be
displayed until the accumulators have been replaced.
After testing the accumulators, reset the test alarm (press button Reset r briefly) and retract all actuators
again.
iA quick check of the accumulators with low load takes place automatically every 60 minutes.
− The end user, i.e., the final owner, has to return used batteries / accumulators to a distributor or public
waste management company. This obligation to return applies regardless of whether it is a private or com-
mercial end user.
− If the system needs to be put out of service / temporarily shut down, the accumulators have to be dis-
connected and the mains voltage has to be switched off!
− Accumulators that are charged but not yet connected have a shelf-life of about 6 months. They must be
recharged if stored for a longer period.
!Actuators must not be actuated directly (e.g., with external accumulators during installation / maintenance)
when they are already connected. This can lead to defects in the power output.

5Detection of fault / Troubleshooting
5.1 General instructions
Occurrence of a fault is indicated by flashing of the indicator s in main alarm points and in the device. With the
help of the service display, the cause can be limited (see 5.2).
● The following are detected as faults:
− Accumulator or mains failure, accumulator polarity reversed
− Failure of the fuses F1 to F3
− Wire-break or short-circuit of the signal lines
− Wire-break or short-circuit of the actuator line (unbranched common line)
− Maintenance overdue (if the maintenance indicator was enabled)
● Notify the maintenance company in case of faults.
● Spare material: In the device, there is a bag of spare fuses and resistors.
● Automatic calibration in case of a fault in the signal line T: After rectifying a fault that was present for
more than 10 minutes, the line is automatically calibrated. The indicator s flickers for about 15 s. If the indi-
cator s then lights up continuously, there is another fault.
5.2 Service display
● Operating conditions can be accurately displayed with the help of the service display.
The display is switched off in normal condition. It can be switched on for 120 s by pressing the button Reset S
for 4 s.
● If there is no alarm / fault message pending, the memory content of the display can be shown for 1 s by briefly
pressing the button Reset r (alarm memory) or the button Reset S (fault memory).
● In case of alarm, fault or automatic closing, the display is switched on, but switched off again after 10 s in the
event of a power failure. In this case it can be switched on again for 10 s by pressing the button Reset S for
4 s.

Actuators must not be actuated directly (e.g., with external accumulators during
installation / maintenance) when they are already connected. This can lead to
defects in the power output.
In case of wrong travelling sense,
reverse polarity of actuator cable.
