SERVICE
CHECKING THE FUNCTION, CLEANING, REPAIR
Installation information
The assembly must be made in a way that the inner viewing,
cleaning and maintenance of the smoke extraction blade dam-
pers is possible. To this end, suitable inspection openings must
be provided in the connected smoke extraction ducts, if requi-
red. The connection to smoke extraction ducts made of wall
boards is done according to inspected duct-specific construc-
tions. The connection to inspected sheet steel ducts or flexible
connection pieces is done via the profiled mounting frame type
PAR.
Regulations for use and maintenance
- -
The operator of the smoke extraction installation must
ensure that smoke extraction blade dampers are always kept
in a ready-to-operate state and are maintained.
- Smoke extraction blade dampers must undergo maintenance
at a six-month interval. If two consecutive inspections do not
show any malfunctions, the maintenance interval of the
smoke extraction blade dampers can be reduced to once a
year.
- An inspection report must be produced, and the documents
must be kept by the operator of the smoke extraction instal-
lation.
The smoke extraction blade dampers must be installed in ac-
cordance with the technical documentation, installation,
mounting and operating instructions.
The work must be carried out by specialised companies only.
Observe general accident prevention regulations.
The smoke extraction blade dampers must be installed such
that they are accessible.
For internal inspection and cleaning of the smoke extraction
blade dampers, install inspection openings in the continuation
connection lines.
The cover of the temperature-resistant actuator housing can be
dismounted for electrical wiring and must be properly remoun-
ted (screwed) once the wiring is completed; the actuator itself
is maintenance-free.
The electrical line installation must be at least E30, according to
DIN 4102-12.
All electrical connections between actuator and power supply
must be made according to the valid VDE guidelines.
Observe the general guidelines for service according to DIN
31051 and EN 13306.
For and after commissioning, the function of the entire smoke
extraction system (interaction of all components) must be regu-
larly checked and documented in writing.
The owner or operator must check whether the minimum re-
quirement for his operation is met.
The function can be checked from the central unit.
Repair work can be carried out only after consultation with the
manufacturer.
1 - Inspection for commissioning on site
Check the smoke extraction blade damper for damage.
The smoke extraction blade damper must be installed in ac-
cordance with the technical documentation, installation,
mounting and operating instructions.
Dismount the cover of the temperature-resistant actuator hou-
sing.
The electrical wiring is done by a skilled electrician. Cable is in-
serted via a bore of exact fit = ø E90 or ø E30 cable through the
side wall of the temperature-resistant actuator housing.
The smoke extraction blade damper is in closed position, blade
dampers "CLOSED".
Connection to electric circuit
*Motors EK10 (SEL 1.90; 24 V AC/DC) / EK11 (SEL 2.90; 230 V AC):
2-point activation of the smoke extraction blade damper.
*Motors EK12 (SEL 1.90 SLC; 24 V AC/DC) / EK14 (EK12 + SPMa-
1SR): activation via 2-wire connection (SLC system) only in
connection with communication device e.g. SPLM-4S 0SD Mod
/ SPMa-1SR (component of EK14).
From the switch cabinet, give pulse for open position (smoke
extraction) or closed position (fire).
Blade dampers (parallel) move to open/closed position; the
movement is controlled by motor.
Limit switches integrated in the actuator indicate the o-
pen/closed positions.
Open / close running time < 60 sec.
*Torque monitoring: SLC system at least 40 Nm.
Screw the cover of the temperature-resistant actuator housing
again.
2 - Service for commissioning on site
Remove / clean dirt / soiling detected during inspection.
3 - Inspection after commissioning – every 6 months / once a
year
See Inspection for commissioning.
Functional test of the smoke extraction blade damper on site.
Functional test by external monitoring.
4 - Service after commissioning depending on system
equipment and operating conditions
Internal inspection
Remove / clean system-specific dirt / soiling which affects sa-
fety function.
Measures to be implemented for service must be docu-
mented in writing and provide proof.
5 - Repair
Repair work must be carried out after consultation with the
manufacturer.
