NTRODUCTION
Delta DE212 is a deadman system for aircraft refuelling trucks and dispensers. The DE212 system can operate
wireless or wired and different sensors can be connected.
This document describes the CU212-1S, the control unit installed in the drivers cabin. Connected to the wired
deadman and the DP sensor.
The wired deadman differs from the wireless as it needs a cable connection between the two units to carry the
needed signals.
The CU212 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.
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 connection of wired deadman override and external
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.
