1.3 Safety Precautions

WARNING: Do not perform maintenance or repair on the Collision Sensor with air

pressure applied, current supplied to the sensor, or the robot not in a safe condition.

Injury or equipment damage can occur if this is not observed. Always ensure that air

pressure has been vented from the unit, that electrical current is not supplied to the

Collision Sensor's signal circuit, and that the robot is in a safe, locked‑out condition

consistent with local and national safety standards before performing maintenance or

repair on the Collision Sensor.

WARNING: The Collision Sensor is only to be used for intended applications and

applications approved by the manufacturer. Using the Collision Sensor in applications

other than intended will result in damage to Collision Sensor or end‑of‑arm tooling and

could cause injury to personnel.

CAUTION: Do not adjust or remove either of the (2) set screws installed in the wall of

the body. Doing so may result in damage to the unit or failure of the switch to operate.

The Collision Sensor is connected to the user's control wiring as a normally‑closed, dry‑contact switch.

The following sketch details the connections between the internal switch and the pins in the connector

block assembly. Optional mating cables, available from ATI (refer to 10), utilize the brown‑black‑blue color

code indicated.

CAUTION: The user is responsible for connecting the collision sensor to their controls

and providing an "electrical load" in series with the collision sensing switch. The switch

is rated for instrument level signals of 100mA (max.) at 10–30VDC.
