1. INTRODUCTION
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.

2. INSTALLATION
2.1 INTRODUCTION
The CU212 DP control unit is designed to monitor the DP Gauge modified by a switch or a sensor.
The control unit is available in two versions:
a) Art.no. 02358, prepared for reading of a DP reed switch NO or NC.
b) Art.no. 02865, prepared for reading of a DP proximity sensor or mechanical reed switch NO or NC.
2.2 INSTALLING THE CONTROL UNIT
The control unit should normally be placed in the drivers cabin. It must be installed outside EX area. Make sure
that the control unit is easy accessible for service.
The control unit CU212-1S, has two cable glands. One is for the input signal from the deadman handle, the
second is for input power and for output and input signals.
It is recommended to use 0,5 to 0,75mm2 cable, and to use soft and multicore cables.
When connecting the cables, take off the two connectors, from the printed circuit board, and connect the
cables to the connectors while they are free to move and easy to keep in the right position.
When all cables are connected, replace the connectors to the printed circuit board and fasten the front panel
to the bottom section.
The installation of the control unit is now finished.
The cable used for the deadman handswitch is normally a coiled cable, witch can be stretched to about 14m.
Normally on an installation, the coiled cable is connected to a connection box, positioned at a central place of
the dispenser, where the operator can reach all the needed positions by stretching the coiled cable. The cable
between the control unit and the connection box is not a part of the delivery.

2.6 DP, DIFFERENTIAL PRESSURE INPUT P3-2.
This function is added in order to prevent refuelling after a high DP signal is detected. The
input signal can be generated by a ON-OFF switch or a Namur inductive proximity sensor.
On CU220 art.no. 02865, the input terminal P3-2 is prepared for both versions.
The difference of the two types of sensors require two different way of connections:
a) DP, ON-OFF sensor. This is a mechanical switch or a reed relay. One solution has a
NO (normally open) situation when the DP is not activated, and the other has a NC
(normally closed) situation when the DP is not activated. In both cases a reference
resistor, Rref, must be connected, see below.
b) Namur inductive sensor, see connection diagram below.

3.4 MAINTENANCE
This equipment should be kept as clean as possible at all times.
Physical damages that may result in cracks or holes on the cabinets should be repaired as soon as possible by
competent personal. This, because there is a large risk of humidity, dirt and oil entering the unit. If the unit is,
for example, exposed by hydraulic oil, it may cause severe damage on the circuit board. Hydraulic oil and
other thin oils are largely penetrable, especially when the equipment housing is damaged. Dirty equipment
should therefore always be cleaned.
As a rule, the equipment should be sent to service as quick as possible when such damages occurs, without
waiting till the equipment does not work any longer - it might be too late to do any repairs.
