Description Of Operation - Seav LR 2299 Serie Bedienungsanleitung

OPTIONAL MODULE RTX 2278 ( BASIC)
It is possible to select four different operating frequencies, all
within the 868 MHz band.
The selected operating frequency must be set in the same
manner on either the memorised RTX2278 (Base) or the RTX
2252 (Sensor) devices.
Use Dip Switch SW1 on both the RTX 2278 and RTX 2252
devices to make the selection.

ESCRIPTION OF PERATION
The RTX 2278 (Base) device controls one, or at most, two RTX
2252 (Sensor) devices, through radio-frequency, for the
connection of sensitive edges. It is possible to view two menus
with the RTX 2278 (Base) Device:
−
MONITOR MENU
−
PROGRAMMING MENU
With the MONITOR MENU and an acoustic signal (Buzzer), the
Device reports the following information:
A :
LARM SIGNAL
Led on + Acoustic signal.
This lets you know which one of the memorised RTX 2252
devices the alarm refers to. A short Beep sounds every time a
reference Led lights up.
---------------------- MONITOR MENU -----------------

1) SENSOR 1 CODE No Alarm
2) SENSOR 2 CODE No Alarm
L :
OW BATTERY SIGNAL
Led On (brief flashes) + Acoustic signal.
This lets you know which one of the memorised RTX 2252
devices has low batteries. In addition to the acoustic signal
whenever a reference Led lights up, two brief Beeps also sound
every minute.

Check the Preselected Operating Frequency
Before programming the transmission code for RTX 2252
(Sensor) Transceivers combined with a RTX 2278 (Base)
Transceiver, it is necessary to select one of the four available
frequencies
paragraph). It is then advisable to make sure that the
preselected band is free (not already in use by another device).
To carry out this check, do the following: using the SET key,
5Vdc
move to the PROGRAMMING MENU; the Base scans the
25 mA
preselected frequency and if it is already occupied by the Base
the MONITOR LED and PROGR. MENU LEDs will flash
2
alternately. In this case proceed to select a different frequency
(on both the Base and Sensor). If, on the other hand, the
selected frequency is free, proceed with programming the
Sensors associated with each channel, as described below.
Programming Keys and Signal Leds
SEL key: this selects the type of function to be memorised, the
selection is indicated by a flashing LED. Repeatedly press the
key to select the desired function. The selection will remain
active for 15 seconds indicated by a flashing LED, after which
time the device will return to its original state.
SET Key:
- this is used to choose between the Monitor Menu and the
Programming Menu: if the SEL and SET keys are not used, the
Monitor Menu will be automatically selected after 1 minute of
inactivity.
- this programs the function selected using the SEL key.
Signal Led
Led on: option memorised.
Led off: option not memorised.
Flashing led: selected option.

SENSOR 1 CODE ( Programming for transceiver RTX
2252 Sensor no. 1)
Programming for the transmission code of Transceiver RTX
2252 (Sensor) no. 1 combined with a RTX 2278 (Base)
Transceiver must be carried out as follows: press the SEL key,
the SENSOR 1 CODE LED will start flashing; in this phase the
Base communicates in broadcast mode with all installed
sensors, looking for one that can be memorised: press the SET
key for the Sensor you wish to memorise to send the
memorisation confirmation code ( the TX LED of the Sensor will
flash quickly 5 times); the SENSOR 1 CODE LED will stay on
steady and programming is finished. The Base device exits
programming if no confirmation code is received within 15
seconds.
Deletion: The memorised code can be deleted as follows:
press the SEL key, the SENSOR 1 CODE LED will start
flashing. Press the SET key, the SENSOR 1 CODE LED will
switch off, and the procedure is finished.
