Operating instructions
4.
Action: Choose between “OK = open” (N.O., working contact) or “OK
= contact” (N.C., break contact).
ü
Configuration of the digital inputs completed.
8.2.2 Output side
Depending on the equipment, you can connect the device to a range of
actors in the alarm chain. The following connection methods are availa-
ble.
8.2.2.1 Bugle
The basic configuration of the device includes a bugle relay to which a
signal bugle or siren can be connected.
Perform the following steps:
1.
In the main menu under System > Outputs, navigate to the “Bugle”
tab.
2.
In the “Bugle” tab, configure the output and state the following infor-
mation.
3.
Action: Choose between “normal opened” (N.O., make contact) or
“normal closed” (N.C., break contact).
4.
Latching: On = The alarm is active, until it is manually confirmed. OFF
= The alarm is deactivated automatically as soon as the limit value
has been undercut.
5.
Relay triggers with: Chose whether this alarm should trigger at limit
value 1 or limit value 2. You can determine the limit values for every
sensor. See section 8.2.1.1 “Sensors” on page 18.
6.
Alarm delay: Determine how many seconds after the exceeding of
the limit value the alarm should be activated.
ü
Configuration of the bugle completed.
8.2.2.2 Limit values
You can set the action of the connected signal technology individually.
The limit values set here apply to sensor 1/output 1 and sensor 2/out-
put 2.
Perform the following steps:
1.
In the main menu under System > Outputs, navigate to the “Limit
values” tab.
2.
Working in the “Limit value” tab, configure the action of the various
output circuit boards and the connected signal technology.
3.
Action: Choose between “normal opened” (N.O., make contact) or
“normal closed” (N.C., break contact).
4.
Latching: On = The alarm is active, until it is manually confirmed. OFF
= The alarm is deactivated automatically as soon as the limit value
has been undercut.
5.
Alarm delay: Determine how many seconds after the exceeding of
the limit value the alarm should be activated.
ü
Configuration of the limit values completed.
8.2.2.3 Digital output signals
You can control the connected signal technology with digital output sig-
nals. Only output 3 and output 4 are freely-configurable.
Perform the following steps:
1.
In the main menu under System > Outputs, navigate to the “Digital”
tab.
2.
In the “Digital” tab, configure the output and state the following infor-
mation.
3.
Function: Enter a name (e.g. ChlorStop or sprinkler installation).
4.
Action: Choose between “normal opened” (N.O., make contact) or
“normal closed” (N.C., break contact).
5.
Latching: On = The alarm is active, until it is manually confirmed. OFF
= The alarm is deactivated automatically as soon as the limit value
has been undercut.
6.
Trips with: Select which message (e.g. limit value, switch of a digital
input, service message) of the output should be triggered.
7.
Alarm delay: Determine how many seconds after the exceeding of
the limit value the alarm should be activated.
ü
Configuration of the digital outputs completed.
8.2.2.4 Analogue output signals
You can issue the sensor values via analogue signals and arrange for their
external evaluation.
Perform the following steps:
1.
In the main menu under System > Outputs, navigate to the “Ana-
logue” tab.
2.
In the “Analogue” tab, configure the output and state the following in-
formation.
3.
Type: Configure the signal. The configuration required depends on
the device connected.
4.
Output: Select the sensor for which the values are to be outputted.
5.
Minimum: Establish the sensor value at which the signal should be at
its lowest.
6.
Maximum: Establish the sensor value at which the signal should be
at its highest.
i
The values for “minimum” and “maximum” serve the scaling
of the analogue output signal.
Example: Sensor 1 has a measuring range of 0 - 10 ppm.
4 - 20 mA was selected as the 20 mA type. If the complete
sensor measuring range is to be covered by the analogue sig-
nal, 0 ppm should be selected for “Minimum” and 10 ppm for
“Maximum”. At 0 ppm, a 4 mA signal will be issued; at 10 ppm
a 20 mA signal will be issued.
7.
Testsignal: You can test the configuration of the analogue outputs.
Read the value displayed on the external device.

Configuration of the analogue outputs completed.
