10.3 - DEVICES ADDITION OR REMOVAL
Devices can be added to or removed from an automation which is auto-
mated with WS200S at any time.
Caution! – Do not add devices before you have checked that they
are fully compatible with WS200S; for details please refer to the
NICE Support Service.
10.3.1 - ECSBus
ECSBus is a system which allows you to connect ECSBus devices using
only two wires which carry both the power supply and the communica-
tion signals. All the devices are connected in parallel on the 2 wires of the
ECSBus itself; each device is individually recognised because a univocal
address is assigned to it during the installation.
The control unit, via the appropriate recognition phase, identifies one by
one all connected devices and is able to detect with extreme safety all
possible faults. For this reason, each time a device connected to ECSBus
is added or removed the control unit must go through the recognition
process; see paragraph 10.3.3 “Recognition of other devices”devices.
10.3.2 - STOP input
STOP is the input that stops movement immediately, (with a brief reverse
of the manoeuvre). Devices with output featuring normally open “NO”
contacts and devices (for instance, the KS100 selector switch), and with
normally closed “NC” contacts, as well as devices with 8.2k
Ω
constant
resistance output, like sensitive edges, can be connected to this input.
Multiple devices, even of different types, can be connected to the STOP
input if suitable arrangements are made; see
Table 7
.

device type:
Note 1.
NO and NC combinations are possible by placing the 2 contacts
in parallel, taking care to place a 8.2k
Ω
resistance in parallel to the NC
contact (thus enabling the combination of 3 devices: NO, NC and 8.2k
Ω
).
Note 2.
Any number of NO devices can be connected to each other in
parallel.
Note 3.
Any number of NC devices can be connected to each other in
series.
Note 4.
Only two devices with 8.2k
Ω
constant resistance output can be
connected in parallel; if needed, multiple devices must be connected “in
cascade” with a single 8.2 k
Ω
terminal resistance.
Caution!
–
If the STOP input is used to connect devices with safety
functions, only the devices with 8.2 kΩ constant resistance output
guarantee the failsafe category 3.
As in the case of ECSBus, the control unit recognises the type of device
connected to the STOP input during the self-learning phase; after which
a STOP command is activated whenever a variation with respect to the
learned status is detected.
10.3.3 - Recognition of Other Devices
Normally the recognition of the devices connected to the ECSBus and
the STOP input takes place during the installation stage. However, if new
devices are added or old ones removed, the recognition process can be
gone through again by proceeding in the following way:
01.
On the control unit, press and hold the P2 button (
fig. 34
)
,
for at
least three seconds, then release the button.
02.
Wait a few seconds until the control unit has completed the device
recognition procedure.
03.
When the recognition procedure has completed, the P2 LED (
fig. 35
)
will go off. If the P2 LED flashes, it means that an error has occurred;
see section 10.5 “Troubleshooting”.
04.
After you have added or removed any devices, the automation sys-
tem must be tested again according to the directions contained in
paragraph 8.1 “Testing”.

10.3.4 - Optional photocells addition
At any time, you can install additional photocells in addition to those
already provided as standard with WS200S. In an automation with sliding
gates, it is possible to place them as shown in
fig. 37
.
For correct photocells recognition by the control unit, you need to carry
out its addressing, through the use of suitable electrical jumpers. The
addressing operation must be carried out both on TX and RX (setting
the electrical jumpers in the same way) and by making sure there are
no other couples of photocells with the same address. The photocells
addressing serves both for correct recognition by other devices on the
ECSBus, and to assign the function performed.
