The Menu Men - Technische Alternative ESR 31 Mode D'emploi

MEN
The menu
The menu contains basic settings to specify additional functions such as sensor type, func-
tion check, etc. Navigation and changes are done as usual with the keys , while the
dialogue is only set up in the text line. As the settings in the menu can change the basic
features of the control unit, only a technician who has the code can open this level.
ENGL Language selection: The entire menu can be switched to the desired user lan-
guage even before the code is provided. The following languages are available:
German (DEUT), English (ENGL).
CODE Code number for entering the menu. The rest of the menu items are only dis-
played once the correct code number is entered.
SENSOR Sensor menu: indication of the type of sensor or a fixed temperature for an input
that is not used.
SYS PF System protective functions: CET switch off the solar thermal system when a
critical collector temperature has been reached; FROST anti-freeze function for
the collector.
STARTF Start function: start help for solar thermal systems.
ART After-running time: can be set for the output.
PSC Pump speed control (only for speed version VD)
COP Control output (0-10V / PWM)
As analogue function (0-10 V): output of a voltage between 0 and 10 V.
As fixed value of 5V to supply vortex sensors without data link connection.
As PWM (pulse width modulation): output of a frequency. The duty cycle (ON /
OFF) conforms to the control signal.
Error message (switchover from 0V to 10V or inversely from 10V to 0V)
F CHCK Function check: activates a monitoring function to detect various errors and critical
situations.
HQC Heat quantity counter - activate and make settings
EXT DL External sensor values from the DL bus.
Sensor type:
PT, KTY Temperature sensors. In the factory settings, all inputs are set to PT(1000).
GBS Radiant sensor GBS (can be used for the start function)

S3 25 Fixed value: e.g. 25°C (using this settable value instead off measured tempera-
ture)

S3 S1 Transfer of values. Instead of a measured value the input S3 receives its (temper-
ature) information from input S1. In addition it is possible to assign values from ex-
ternal sensors (E1 to E6).
DIG Digital input: such as when a volume flow switch is used.
OFF The sensor is not displayed on the main level
VSG Volume flow encoder (pulse encoder): Only on input 3, to read-in the pulses from
a volume flow encoder (determination of the flow rate for the heat quantity counter)
Litres per pulse = the volume flow encoder's pulse rate (only when sensor type S3
LPP
= VSG). (ex works = 0.5)
Setting range: 0.0 to 10.0 litres/pulse in increments of 0.1 litre/pulse
WS Wind sensor: Only connected to input S3, to read in the pulses of the wind sen-
sor WIS01 from Technische Alternative (1Hz per 20km/h).
