8K2/C

ONTACT FUNCTIONING MODE SELECTION

The RTX 2251 (Base) device selects the CH1 and CH2 relay
control outputs.

Selection is through Jumper 1 – 2:

ON

J1 pos. 1-2 = NC CH1 relay output (default).
J1 pos. 2-3 = 8K2 CH1 relay output.
J2 pos. 1-2 = NC CH2 relay output (default).
J2 pos. 2-3 = 8K2 CH2 relay output.

DEVICE TEST

The RTX 2251 (Base) device has a "Test" input to be used
when the control unit it ‘s coupled with is equipped with Safety
Devices test function. Test is performed as follows: the control
unit must switch the signal in "Test" input from high logic level
(12-24 Vac-dc during normal functioning) to low logic level: the
RTX 2251 device must respond varying the state of the two
CH1 and CH2 channels outputs to pass the test.

C

ONTROL OF THE SELECTED FREQUENCY

Before programming the RTX 2252 (Sensors) codes associ­ated to the RTX 2251 (Base) it’s necessary to select one of the
four frequency channels available (see paragraph “Functioning
Frequency selection”) and it’s advisable to verify that the chan­nel selected is free; to do that proceed ad follow: with SET but­ton go to PROGRAMMATION MENU; the Base makes a scan­ning of the channel selected and if it’s busy the Base will sig­nalize this with an alternately flashing of LED MONITOR and
LED MENU PROGR.. In this case choose an other frequency (
on Base and on Sensor). If the channel selected is free, makes
the programming of the Sensor as indicated in the next para­graph.

ROGRAMMING KEYS AND INDICATOR

LEDS

SEL Key: selects the type of function to memorise, the choice

is indicated by the flashing of the LED. Repeatedly press the
key to position oneself on the desired function. After 15 sec­onds of activation displayed by the flashing LED, the device
returns to original state.

SET Key:

- selects between Monitor Menu and Programming Menu: the
Monitor Menu is automatically selected after 1 minute of SEL
and SET keys inactivity.

- programs the function chosen with the SEL key.

Indicator LED

LED on: option memorised.
LED off: option not memorised.
Flashing LED: option selected.

CH1 of RTX 2251 (Base) Transceiver Device, is programmed
as follows: press SEL and CODE 1 CH 1 LED starts flashing;
the Base broadcasts to all Sensors, searching for one to be
memorised: press SET key of the Sensor you want to program
to send the memorisation confirmation code ( TX LED makes 5
quick flashes); CODE 1 CH LED remains on and programming
is complete. The Base device exits programming if no confir­mation code is received within 15 seconds.

Deletion The memorised code is deleted as follows: press
SEL and CODE 1 CH1 LED starts flashing; press SET, CODE
1 CH1 LED switches off and the procedure is complete.
