INTRINSICALLY SAFE PASS-THROUGH SIGNAL SPI-89/1

THE SPI-89/1 INTRINSICALLY SAFE PASS-THROUGH SIGNAL PROVIDES:

• emergency shutdown of drives,
• location of the damaged section of the transmission line.

The drive is switched off and locked using a rotary switch or by pulling a cable mechanically coupled to the switch. The switch-off signal is sent by the identification pulse transmitter to the SBI-89/1 signal, where the number of the through signal in which the switch-off was made is displayed. The location of the damaged section of the transmission line is achieved by pressing the appropriate button on the subsequent through signalers and observing the light-emitting diodes.
