2.6.2.d Retriggering function (deadlock)
The M-SHEV product family meets the requirements of
prEN 12101-9 with regard to deadlock, e.g. frozen NSHEVs
(natural smoke and heat exhaust ventilation). This means that
after an ALARM triggering, the actuators are actuated
15 times in the OPEN direction. A new start attempt is made
with initial short closing for 3 seconds in the CLOSE direction
(to protect actuators without restart interlock) at intervals of
2 minutes. A waiting time of 500 ms is observed between
each change of direction. After 30 minutes the triggering
OPEN remains active.
The re-triggering function is switched off by
default and can be individually enabled for each
MR-120.
2.6.2.e Alarm ONLY with analog input (optional) —
Dependency logic
With this function, the analog input is used with
the aid of an external analog circuit as an addi-
tional condition for the execution of a ventilation
function (dependency logic). For this purpose, the analog
input (terminal "+") is permanently checked for a continuous
signal (min. 0.8 mA). As long as the signal is present, an
ALARM function can be performed. If this is not the case,
none of the connected actuators is electrically controlled
2.6.3 Ventilation functions
The ventilation functions are only enabled in mains operation;
if the system switches to emergency power operation, no new
ventilation commands are accepted. Pre-existing ventilation
commands are kept for 3 minutes
2.6.3.a Connection ventilation button /
input ventilation signals
Two ventilation buttons or comparable ventilation signals can
be connected in parallel to the M-SHEV. The behaviour of the
ventilation function is influenced by the triggering type and
duration.
It is possible to use input signals from other
modules.
2.6.3.b Action behaviour of ventilation buttons
The dead man’s function activates automatically if the venti-
lation button is pressed for more than three seconds (auto
dead man’s function). The dead man’s function is a safety
function in which the actuators only move as long as the
respective direction button is pressed. The actuators stop as
soon as the button is released.
If the ventilation button is touched only briefly, the ventilation
command is switched to continuous triggering. A stop func-
tion is achieved by briefly re-pressing the ventilation button in
the OPEN direction, e.g. when opening (tip-stop function).
Each motor relay can be readjusted per ventila-
tion button connection (LT1 / LT2, mode open /
close) ) as follows:
• auto dead man + tip-stop
• auto dead man
• no dead man + tip-stop
• no dead man
• dead man only
2.6.3.c Open delay in vent mode
The MR-120 allows you to set a start delay for
certain applications (e.g. in combination with sun
protection systems in front of windows). This
ventilation triggering will be displayed immediately, received
and processed and can be indicated by a MI-100 signal inter-
face. After the intended ventilation start delay time has been
elapsed, the actuators move to the intended ventilation posi-
tion.
2.6.3.d WTS (wind / rain-detector)
For each motor relay it can be defined whether it
should react to the central WTS signal (ZI-100).
2.6.3.e Gap ventilation
The gap ventilation function allows the user to
open the smoke and heat exhaust / vents up to
any defined stroke. The gap ventilation function
and the gap ventilation time can be set with SIMON LINK.
When the ventilation button is pressed, the actuators open to
the set position or to the full opening stroke in ALARM mode.
2.6.3.f Automatic close
This function closes the opening units automati-
cally following a freely adjustable ventilation time.
This function is used to set the waiting time after
which the drives are to be closed automatically. This setting
can be parameterized in seconds (s), minutes (min) or hours
(h) up to a maximum of 24 hours.
ATTENTION
The continuous signal is only detected from 0.8 mA. The
maximum current at the input must not be exceeded!
This input is deactivated by default.
INFORMATION
The ventilation functions can be modified on request using
the SIMON LINK configuration software.
INFORMATION
If you change a setting at this point, please remember to
apply a functionally identical settings to the ALARM func-
tions (see chapter 2.6.2.a “Open delay in alarm mode” on
page 13).
ATTENTION
A new OPEN command is only accepted by the MR-120
after the CLOSE gap ventilation time has fully elapsed.
