Fix values
Fix values can be enabled/disabled and the value be set for the following parameter

•Output x scale low/high - the low and the high value of the measurement parameter is linked to the low and the high range value. E. g. -50Pa -> 4mA and +50Pa -> 20mA.
•Load resistor x [ohm] - Ohmic resistor for the current output used by the device integration at the customer. It is between 0 and 500Ohm.
Display
•Display row x - the measurement value can be linked to the display row.
•Font color - user can chose the color of the displayed measurement value/unit.
•Font color alarm - user can chose the color of the displayed measurement value/unit at alarm.
•Font color pre alarm - user can chose the color of the displayed measurement value/unit at pre alarm.
•Background color - can be set by the user.
•Brightness - can be chosen between 20 and 100.
Alarm
•Device alarms of each measurement parameter can be enabled/disabled
•Lower, upper alarm limit and hysteresis of each measurement parameter can be defined
for the following parameter
•Analog input
•Ambient pressure
•Flow
•Volume flow
Relay
The following configurations can be set for Relay 1-6.
•Relay alarm source x - For each parameter, the user can chose what event switchs the relay on (low alarm, high alarm, low and high alarm or unused)
•Relay off after alarm end - The relay is released with the end of the alarm.
•Relay of after timeout - The relay releases after a timeout independent if the alarm still exists or not.
•Relay on after delay [s] - The relay switches on with a delay after the alarm occurs.
•Relay timeout [s] - The relay switches on with an alarm and off again after the Relay timeout.
•Mute enable/disable - This option enabled mutes an active alarm after the mute delay (see below).
•Mute delay [s] - Time delay after an active alarm is muted.
Analog input
•Analog input default unit - The user can chose between a default or an individual unit for the analog inputs. The default displays V or mA.
•Analog input 1/2 input type - Chose of voltage or current input.
•Analog input low/high range - the min./max. analog input signal is defined.
•Analog input 1/2 low/high scale - to the low/high range above, the low/scale of the measured value is linked. E. g. 400ppm CO2 concentration = 4mA analog input and 10000ppm = 20mA.
Ethernet
Note: The PF4/5 can not be communicate with the Hygrosoft via RS485. The Hygrosoft can only configure the device.
•RS485 adderess
•Modbus mode - Word swap, Byte swap, Byte and word swap, No swap
RS485
•DHCP enabled/disabled
•IP address - Necessary, if DHCP is disable.
Menu protection
If the menu protection is active, the user can only read device information on the device display. He cannot change device settings.
•Menu protection enabled/disabled
•Password - can be set.
Valve
•Autom. 0-point adjust [min] - this feature performs a 0-point adjustment of the differential pressure sensor to compensate long term drifting. This feature can enabled and repeated automatically every set minutes. 43200 is default is stands for every 30 days.
Note: This feature is supported only for the PF5. This feature has no effect on the PF4 operation. The PF4 executes an 0-point correction every measurement interval automatically and sensor internally.
Flow
•Enable flow parameter
•Cross section – see CRP5
•K-Factor – value between 0 – 1. Quotient between max. measureble flow and the average flow over the cross section. As bigger the cross section is as closer the K-factor to 1 is.
