Eltako B4T55E Bus Push Button
Only skilled electricians may install this electrical equipment otherwise
there is the risk of fi re or electric shock!
Temperature at mounting location: -20°C up to +50°C.
Storage temperature: -25°C up to +70°C.
Relative humidity: annual average value <75%.
Bus pushbutton for single mounting 80x80x15 mm. For connection to FTS14TG
pushbutton gateway. Only 0.2 watt stand-by loss.
2-way- or 4-way pushbutton B4T55E-, only 15 mm high.
The scope of supply comprises a mounting base, an attachment frame with
snapped-on electronics, a frame, a rocker and a double rocker.
The double rocker permits entry of 4 evaluable signals, but the rocker allows
only 2 signals. At the rear, a 20 cm long red/black bus line is routed
externally. Red terminal to BP, black to BN of a pushbutton gateway FTS14TG.
Up to 30 bus switches and/or FTS61BTK pushbutton bus couplers can be connected
to terminals BP and BN of an FTS14TG push-button gateway. The permitted
maximum line length is 200 m. The RLC device enclosed with the FTS14TG must
also be connected to the terminals BP and BN on the bus switch or pushbutton
bus coupler furthest away. A voltage of 29 V DC is supplied to the connected
B4 over a 2-wire pushbutton bus which is also used for data transfer. Please
use only conventional bus or telephone lines.
Confirmation telegrams from actuators are displayed by 4 resp. 2 yellow LEDs
when the actuator IDs are entered by the PCT14 in the ID table of the FTS14TG.
Use the sleeves in the 55 mm socket box for screw mounting.
Installation: Screw on mounting plate. First attach the frame and then
snap on the mounting frame with the electronics (labelling 0 must be above).
When you fi t the rocker, the 0 mark on the rear must always be on top. We
recommend stainless-steel counter-sunk screws 2.9×25 mm, DIN 7982 C, for screw
connections.
Both with rawl plugs 5×25 mm and with 55mm switch boxes.
Rocker:
top sends 0x70
bottom sends 0x50
Double rocker:
top left sends 0x30
bottom left sends 0x10
top right sends 0x70
bottom right sends 0x50
Operating mode rotary switches of the FTS14TG:
Pos. 2, 3, 4: Every pushbutton of the B4T55E- has the same ID.
Recommended setting for ES functions with direction pushbutton.
Pos. 5, 6, 7: Every pushbutton of the B4T55E- has a separate ID.
Prescribed setting with ER functions.
Issue device address for B4T55:
-
Connect the first B4T55E- to the BP and BN bus terminals.
The LED on the B4T55E- lights up red. -
Turn the rotary switch on the FTS14TG to Pos. 1.
After the FTS14TG issues the address, its lower LED lights up green. -
Turn the rotary switch on the FTS14TG to Pos. 2 to 7.
The LED on the B4T55E- lights up green. -
Only then connect the second B4T55E- and repeat the procedure from 2, etc.
A device address 0 (as-delivered state) can only be issued to one B4T55E-.
The address is always issued in ascending order 1-30.
When a B4T55E- is replaced and the rotary switch on the FTS14TG is turned to
Pos. 1, the new B4T55E- automatically receives the same device address and the
system runs as before without requiring further teach-in.
Clear device address of a B4T55E-:
-
Connect only one B4T55E- to the BP and BN bus terminals.
The LED on the B4T55E- lights up green. -
Turn the rotary switch on the FTS14TG to Pos. 9.
After the device is cleared, the lower LED on the FTS14TG lights up green and the LED on the B4T55E- lights up red.
LED display:
LEDs off: There is no power supply over the 2-wire bus.
Red LED lights up: Power is supplied over the 2-wire bus. The B4T55E- has no
device address yet or the bus is defective. Green LED lights up: B4T55E- has a
device address and is ready to operate.
Use a jumper to disable the green LED off.
Typical connection
alternatively FTS14KS without bidirectional wireless
The second terminating resistor supplied with the FAM14 or FTS14KS must be
plugged into the last bus user. Use the PCT14 PC tool to make additional
actuator setting options for conventional pushbuttons. An FTS14TG pushbutton
gateway can be connected decentrally to up to 30 B4T55E- bus swit-ches and
FTS61BTK pushbutton bus coup-lers each with 4 pushbutton inputs. A single
2-wire line supplies the pushbutton bus coupler with power and also transfers
the pushbutton data. The user may select any topology for the 2-wire
connection.
The RLC device enclosed with the FTS14TG must also be connected to the
terminals BP and BN on the bus switch or pushbutton bus coupler furthest away.
