3.8 Initial operation of the ProFLECT II i – Anti-trap protection
Upon delivery, the actual weight ratio regarding the ceiling closing plate is still unknown. The anti-trap
protection is therefore not yet set correctly. After the installation incl. all covers has been completed, a test
run needs to be executed, during which the ProFLECT II i will determine all correct values independently. A
slowly flashing LED (orange) indicates the need for a test run.
Caution – Important note:
As long as this LED is not permanently lit, the device is not safe to operate in regard to anti-trap protection!
3.8.1 Implementation of control via RS232 interface
Input signal via RS232:
Protocol settings:
9600, 8 ,n ,1 , local echo on, no flow control
Chain of command:
open [ENTER]: Lift open. Corresponds to “Up” button
close [ENTER]: Lift closing. Corresponds to “Down” button
stop [ENTER]: Lift stops
learn [ENTER]: Test run – please mind the screen
calibrate [ENTER]: Set closing angle – please mind the screen (1)
stat [ENTER]: Showing lift status
(1) The lift will first move towards the open position, if not yet positioned there. Please wait until the
open position is reached. In order to set the closing angle, please confirm by using either “+” or “-”
buttons on the PC keyboard. You may press “+/-” several times repeatedly. Pressing “-” will reduce
the opening angle (lift opens less), using “+” will increase it. If there has been no input for more than
1 second, the lift will accept the new position. Repeat the process as many times as needed until the
lower position has been reached as desired. Then enter “next” [ENTER].
The lift will move to the closing position – please wait until it has reached this position. Then set the
closing point the same way, using “+/-”. Again: pressing “+” will close the lift more, “-” will close it
less. After the closing point has been determined, please enter “next” [ENTER] again. The process is
then complete.
3.8.2 Alternative control (two 24 V power relays) – preparation
First open the cover of the control box. To do so loosen the two crosshead screws and then remove
the cover.
Alternative control (two 24 V power relays) – Moving up and down
Two switches are required as control elements, each with a shutter that close at+24V. The electric
current is approx. 10mA. External voltages can be used. For that purpose, “0V” of the PCB board
needs to be connected to the reference of the external voltage. Input voltages between +5V and
+24V DC are permitted.
The corresponding terminals are indicated on the PCB board by “Up”, “Down” and “+24V”. “Up”
closes the ProFLECT II i, “Down” will open it.
Pressing a button causeses the ProFLECT II i to move to the corresponding direction. It is not
necessary to press and hold the button. The ProFLECT II i will stop automatically after it has
reached its final position. In order to stop the ProFLECT II i earlier, press the button of the opposite
direction.
