• OPERATION
The RTX 2252 device (sensor) allows the connection of safety bands of the classic type
NC (normally closed contact) or 8K2 Ohm resistive type.
This sensor operates only in combination with the control base - 2278 RTX.
The device is powered with stacks, avoiding any cable connection.
After stored in RTX 2278 device, sends you the following information:
•
Survival signal:
Check periodically if the radio connection between the devices is
functioning properly and informs the base.
•
Alarm signal:
Tells the basis that the safety device is activated.

When the inhibitor input is not used, it should always be made a bridge
(jumper) between 3 and 4 inputs.

Discharged stack signal:
Tells the base the stack status.
Operation with Contact Inhibitor:
The RTX 2252 device (sensor) enables the connection of a contact (NC) for temporarily
inhibiting of the safety band connected to the sensor.
With the application of one micro-switch (CN1, connector 3 and 4), the band can be
disabled for the motor does not reverse when it reaches the end of the closure and
presses the band.
Aplique 1 micro (NC), de forma que comute para NA centímetros antes da banda com-
primir.
In this case, the band can be pressed without causing reverse movement.
