2Dimensions and mounting
Mounting of the unit in the cabinet front door is made by cutting a rectangular
hole, 203x115 mm. The unit is then fixed with two metal brackets and
4 screws on the backside of the front door.

4Electrical connection
4.1 Power supply 24 VDC or 27,2 VDC
PC-2000-W is powered with a stabilised 19.2-30VDC supply, same power supply
as the CPU unit ADA-2000-E. If battery backup is used the power supply must be
able to deliver 27.2VDC in order to recharge the battery. Depending on how much
load there is on the 24VDC circuit we recommend to use a 24VDC battery with
1.3-3Ah capacity.
If the utility power has problems with transients due to atmospheric charges etc. a
surge protection device should be installed at the 230 VAC supply line.
If the utility power has problems with unstable supply voltage (over/under voltage)
it is recommended to install a stabilizer device at the 230 VAC supply line
Figure 4.1 Shows a power supply with or without battery backup. Protect the 24 VDC
circuit with a 1 or 2 ampere fuse.

4.2 Signal connection between PC-2000-W and ADA-2000-E
To connect the signals from the I/O unit ADA-2000-E with the operator unit
PC-2000-W, two band cables for the digital signals and one screened round band
cable for analogue signals are used.
Below is explained how these cables are connected to the units and the signals.
-Band cable CSD20/1.5m is connected between K2 on ADA-2000-E and K8 on
PC-2000-W, this cable is used for the digital outputs 12 to 16 and for the digital
inputs 11 to 20.
-Band cable CSD26/1.5m is connected between K1 on ADA-2000-E and K9 on
PC-2000-W, this cable is used for digital outputs 1 to 11 and digital inputs 1 to 10,
and digital pulse counters 1 and 2.
-The screened round band cable CSA14E/1.5 m is connected between K3 on
ADA-2000-E and K10 on PC-2000-W. The ground wire of the cable shall be
connected to the earth terminals on ADA-2000-E and PC-2000-W. The cable is
used for the analogue inputs 1 to 7 and the analogue outputs 1and 2.
Picture 4.2 Shows how the
signal the cables are connected
between the PC-2000-W and
the ADA-2000-E.The screened
analogue signal cable has it´s
own separate ground wire which
connects the front panel mounted
PC-2000-W to the ground.

5Communication with PC-2000-W
5.1 Communication ports
The pump controller PC-2000-W has three communication ports. The RS232 port
which is used for communication with GSM/SMS modems or for communication
with SCADA-systems, The RS485 port is used for serial communication with
other PC-2000-W or other type of controllers and instrumentation. The unit has a
CAN-bus which is not used at present.
5.2 RS232. Direct serial communication to a computer.
The PC-2000-W can be directly connected to a PC computer via a 9 pin D-sub
connector to RS232-terminal on PC-2000-W. This connection is made as shown
below and can be is used with the DripDrop configuration software PC-COM.

5.3 RS232. Modem communication with GSM, GDW-11.
Below you see how a Westermo GDW-11 GSM modem is connected for GSM
communication and SMS sending. Note that the digital output number 16 is used
as modem control to restart the modem via the PC-2000-W. Below you see the
connections between the PC-2000-W RS232 connectors and the terminals of the
modem.
