Circuit

If an alarm condition from either 'Upper difference' or 'Lower difference' is
present for a longer time than the set delay (in min.), the alarm function
is activated.
1 ... 99 m: The alarm function will be activated if the alarm
condition remains after the set delay.
Lowest temp.

The alarm function will not be activated if the desired flow temperature
is lower than the set value.
Alarm overview, in general
Circuit
2
Access to overview showing the alarm number / alarm type. The alarm
number is entered into the alarm register and can be obtained from a
SCADA system.
Example: "3: Temp. monitor": If an alarm is activated because of conditions
in 'Temp. monitor' the alarm number 3 is placed in the alarm register.
S14 pressure — A376.9
Circuit

Access to settings related to pressure measuring via input S14. Actual
measured pressure is shown. Conversion of input voltage to displayed
pressure.
The pressure is measured by means of a pressure transmitter. The
transmitter sends the measured pressure as a 0-10 V or a 4-20 mA
signal. The voltage signal can be applied directly to the input in
question. A current signal is converted by means of a resistor to a
voltage and then applied to the input. The measured voltage must
be converted to a pressure value by the controller.
The following procedure sets up the scaling:
Push the dial to see the graph and enter the value sets for the input
voltage (2 and 10 volt) and displayed pressure (in bar).
Pressure: 0.0 ... 20.0 bar
Fixed voltage settings: 2 V and 10 V
Factory settings: 2,1.5 (= 2 V / 1.5 bar) and 10,13.5 (= 10 V / 13.5 bar)
This means that the 'Pressure' is 1.5 bar at 2 V and 13.5 bar at 10 V.
Typically, the higher the voltage, the higher the displayed pressure.

If the cause of the alarm disappears, the alarm indication and output
also disappear.
This scaling menu is always shown, regardless whether a pressure
transmitter or a pressure switch is used.
