CU212 Control Unit
1. INTRODUCTION
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.

NOTES:
•Input voltage should be 12 or 24VDC. Max 35VDC
•All outputs gives 12/24V out when activated, max 3,5A per output, total load: 5A.
•Note that the potential between the minus pole and ground/GND, must not be greater than 50VDC/AC peak.
•Deadman cable input has no polarity requirements.
•The warning outputs operates as follows: when the deadman function is activated, the warning light is
activated at the same time. When 30 seconds remain of the timer period, the warning light output change
from a steady signal to an intermitted signal during the last 30 seconds of the time period. During the
intermitted signal, the beeper warning goes active, with a steady signal as long as the warning light signal is
intermitted.
2.2 CHANGE OF FUNCTIONS BY SW2.
NOTE: Switch SW2 is located on the printed circuit board inside the control unit.
The state of all 4 single switches of SW2 will be read, stored and activated by the control units
microprocessor if the CODE-button on the front is pressed and hold for more than 3 sec. when
switching on the control unit.
After this 3 sec. the green “ON”led on the front turns on (lights up), indicating that the process
is finished successful.
When the control unit is connected to the power supply, this SW2-reading-process can also
easily be initiated by pulling out the fuse F1/5A and push it back into its socked.
•Deadman function, with or without timer.
This selection will done by SW2-1.
For timed deadman, set SW2-1 to ON. For no timer, set F2-1 to OFF
•Deadman override enabled/disabled
To enable the deadman override input set SW2-3 to ON.
To disable the deadman override input, set SW2-3 to OFF. .
•Type of handswitch, failsafe / not failsafe
The CU212-1S can operate with other handswitches as the failsafe CB212-1S.
If a handswitch with an ordinary ON/OFF switch is used, (not failsafe) the control unit CU212-1S has to be set
for NOT FAILSAFE operation:
To set the control unit for using a failsave CB212-1S handswitch, set SW2-4 to ON
To set the control unit for using a NON-FAILSAFE handswitch, set SW2-4 to OFF
NOTE: The external STOP input is always enabled.

2.3 INSTALLING THE CONTROL UNIT
The control unit should normally be placed in the drivers cabin. It must not be installed in 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, P1 and P3, 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 a 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. See system diagram 1.2.
2.4 CABLE CONNECTION TO HANDHELD UNIT
NOTE: There are no polarity restrictions when connecting the cable.

3.2 FUNCTION DESCRIPTION
CB212-1S, Handheld unit.
The functions of the handheld unit, CB212-1S, is controlled by electronic circuits at the printed circuit board
inside the housing. The handheld unit has two push buttons, one black and one red. The black is the deadmans
button, which can be operated by the lever or the directly to push the button.
The red button is the STOP button, intended for emergency stop of the fuelling process from a remote position.
The electronic has a failsafe design, telling that the system will stop if something goes wrong. That is
for instance if the cable short-circuits. This will immediately shut down the fuelling.
The wired deadman is normally delivered with a timer. When the handheld unit is operated, the fuelling process
is allowed to continue. But only for 2 minutes. Within this time, the operator has to release and re-operate the
handle quick, to make the fuelling continue.
If the handle is not reactivated, the fuelling will stop after the 2 minutes.
The last 30 seconds of the 2 minutes period, two output signals in the control unit can be used to warn the
operator, and tell him that he has to re-operate the handle in order to avoid stopping the fuelling process.

CU212-1S, Control unit:
The front panel has two light diodes, LED's on the front panel. One is marked ON, and the other is marked CH.
The ON is green, and is lit when the power is connected. The CH is yellow and is lit when the deadman switch is
activated. The CODE pushbutton is only for “function-setup/configuration” purposes of the control unit.
Output signals are:
Deadman output: Active when the deadman handle is pressed, and timer is running.
STOP output: When control unit is powered, this output is active, supplying 12/24V. When the STOP
button is activated, this output is switched off. If the cable is shorted, this output is
also switched off.
Warning light output: Is active simultaneously with the deadman output. During the last 30 seconds of the
timer period, it change from a steady signal to intermittent signal.. Is normally used to
drive a lamp, visible for the operator.
Beeper output: During the last 30 seconds of the timer period (the intermittent period of the warning
light output), this output is active. Is normally used to drive a beeper or horn to give a
audio warning that the time period is running to an end.
NOTE: All outputs can supply a current of 3,5A, limited to 5A totally.

3.3 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.
