PS3 CONTROLLER
MANUAL INSTRUCTIONS
For ribbon switches, edges and mats of category 3
- GENERAL INFORMATION
The units of PS-3 series are the controllers for sensitive sensors provided with four
wires (fail-safe condition) to meet category 3, as given by EN 954.
At the open circuit of switch edge, mat, bumper in normal condition, the two relays
are ON, while the pressure on the sensor causes the relays OFF.
The interruption of the cable or the sensor, are detected in OFF condition of two
relays, as the short circuit of the contacts of one relay. For this reason the circuit is
named “fail-safe” and meet category 3 as EN 954.
Is available the manual and automatic reset.
Power supply: 24 Vd.c. 24-110-230 Va.c.
2
Every unit can control 2 or more mats in series with max surface of 15 m or sensors
with a total length of 60 m.
- WORKING PRINCIPLE
The internal circuit can be compared to a N.O. contact. In this condition, the two
relays are in ON state. When the pressure sensor is actuated, a short circuit happens
on the circuit and the two relays are OFF. A limiting circuit of current provides to
protect the different electronic component to avoid the burning of the same.
