Before meeting the SWX (SWO) stop limit switch, braking preset by TSM time will start.
Braking leads the gate/door from standard speed (FSTSO/FSTSC) to braking speed, adjusted by SLDS parameter.
The TDEC time sets how rapidly the gate/door should reach the braking speed.
The TDEC time is theoretical by reason of the fact that as soon as the speed reaches the value preset by SLDS, braking at constant speed starts until
reaching the SWC (SWO) limit switch.
Once the limit switch is reached, the gate/door continues its movement for a period of time adjusted by BLC parameter, until entire stop.
The following diagram graphically represents the stroke of the gate in case of intervention of a safety input (STOP/PHOT/BAR):

T
The intervention of the safety input causes an immediate slowing of the gate, the time in which the gate switches from standard speed to a complete
stop is adjustable through the TBR value and must respect the values indicated in Table 1.
IMPORTANT:
- For the correct operation of parameters it is mandatory that the AUTOSET be carried out correctly (see STROKE LEARNING).
- If the FSTo(FSTc) speed is increased, TSMo(TSMc), TACC and TDEC values must be increased proportionally in order to avert any mechanical stress
to the gear motor.
- The TBR value must be set according to those indicated in table 1, setting a TBR that is too short on a gate with strong inertia may damage the automation.
A TSMo (TSMc) value, which is too short, combined with a TDEC value, which is too high, might result in the cancellation of the SLDo (SLDc) braking
phase due to the gate leaf friction and the triggering of the limit switches when the speed is still high.
This situation must be absolutely avoided.
- The AUTO function does not change the default values of the above-mentioned parameters. The latter must be preset by the installer according to
the gate/door specifications.
- An NC contact that opens whenever the engine is unlocked or the casing is removed will also be serially wired in the BAR input with the SAFETY
EDGE (or the SAFETY EDGES). Thus, in situation 1. unit powered, 2. Engine stopped, 3. SWO and SWC not engaged (i.e. engine out of limit switches),
if the BAR input is activated and then reactivated (engine locked and carter inserted, ready to restart), upon the subsequent PP/OPEN/CLOSE
command (also by radio) it is necessary to force a slow manoeuvre.

Depending on the actuator model and the weight of the gate, set the speed value in opening and closing (FSTO/FSTC), the minimum value of the TBR
braking and the minimum value of the TSMO/TSMC slowdown distance.
At each combination we obtain the value of the speed of the gate (Column V) expressed in meters/minute.
Exceeding the recommended values may cause damage and malfunction, the manufacturer does not assume any responsibility arising from improper
FSTO/FSTC/TBR/TSMO/TSMC value settings.
The values reported are indicative and referred to a standard installation, the installer must nevertheless ensure compliance with the limits set by the
EN 12453, EN 12445 standards.
15) AUTOSET
For a correct operation of braking it is essential that the stroke is memorised. This can be performed either using the above described AUTO function or
when the first operation is completed (then carried out without interruptions) from SWO to SWC (or viceversa).
The engine starts in SLOW mode to search for SWO, it stops, then reverses still in SLOW manoeuvre to search for SWC (determining the stroke). Then
first FAST manoeuvre from SWC to SWO (ramps, speed, slowdowns determined by the TSMo/TSMc/FSTo/FSTc/SLDo/SLDc parameters set) and se-
cond fast manoeuvre from SWO to SWC.
However, these values can be manually modified at a second time.
If you manually change a parameter that requires a new acquisition, the unit will perform a complete opening and closing manoeuvre, the message
"PRG" will be displayed. At the end the operation will return to normal.
It is not possible to carry out the autoset with logic HTR:ON
