Introduction
Parker offers a variety of safety valves for use in various safety functions such as safe exhaust, safe cylinder, return,
and safe load holding/stop. This document focuses specifically on valves that use sensors to provide feedback to a
safety control system for external monitoring.
While all potential electrical safety control suppliers and solutions cannot be covered this document provides a
template for the most common suppliers and their devices.
Each solution has been designed to meet a specific category and performance level based on ISO 13849. Meeting
this levels requires other aspects of the system meet these requirements such as but not limited to plumbing, wiring,
and pulse testing.
Wiring examples are provided in this document and are shown using specific connections as wired and tested, but
there may be other terminals available to use on the various controllers. These are just examples.
This integration guide is intended to assist you in integrating the product into your control circuit however; programs
provided in this integration guide are for reference only. These programs have not been certified or tested unless
indicated otherwise.
Pulse Testing
In dual channel safety circuits, pulse testing is a method utilized to detect short circuit conditions that, without
pulse testing, can mask other fault conditions. Pulse testing of the solenoids is encouraged and will not affect the
performance of the Parker valves. However, pulse testing of feedback sensors is not required.
