Introduction; System Diagram - Delta DE212 Operation And Installation Manual

NTRODUCTION
Delta DE212 is a deadman system for aircraft refuelling trucks and dispensers. The DE212 system can operate
wireless or wired.
This document describes the CU212-1S, the control unit installed in the drivers cabin, and the
CB212-1S, the handheld unit, which are the two main components of the wired deadman.
The wired deadman differs from the wireless as it needs a cable connection between the two units to carry the
needed signals.
The DE212-1S/F wired deadman is designed for failsafe operation.
The DE212-1S wired system is designed to operate the deadman valve and also comprises a stop button on the
handheld unit, making it possible to "emergency-stop" the refuelling from a remote position.
The DE212 has a built in timer system, with timeout warning outputs for light and beeper. The standard timer is
set to 2 minutes with the warning signals 30 seconds before the refuelling will shut down.
If the control unit is connected to a simple ON-OFF handswitch, the control unit has to be set to none failsafe
operation, this can be selected by a qualified technician.
With more than 15 years of experience in developing and producing deadman systems, the DE212 system has all
the security needed for a safe and reliable operation.
For special applications, the control unit has inputs for deadman function override and STOP.
The DE212 system is based on the latest technology and has the flexibility to meet new operational demands by
upgrading the software in the control unit.
