Parameterizations
9.2.1 DIP Switches "LF" and "ADJ"
The front panel of the frequency transmitter contains a 4-pole DIP switch.
*) Default setting upon delivery, **) see following chapter "Input"
The DIP switches "LF1" and "LF2" are used for activating the line fault detection
(see above table) and for resetting the anti-pumping device
(see chapter "Anti-pumping device"), respectively.
The DIP switches "ADJ1" and "ADJ2" allow the minimum and maximum counts of the
pulse counter for channel 1 and channel 2, respectively, to be reset.
Line faults and auxiliary power failure are signalled via LED, error message
contact at the module and collective error message via pac-Bus
(see chapter "Schematic circuit diagrams of up to 2-channel designs").

Changing the DIP switch settings is also permitted during operation in
Zone 2 and with connected intrinsically safe input signals.
The characteristics of the output signal are set by means of the
"ISpac Wizard" software. It also allows the line fault detection to be
completely deactivated. This setting determines the characteristics of the
device, while the DIP switch is completely ineffective in this case.
