Page 8: Overvoltage Protection
CIT 400 / CIT 401 4. Overvoltage protection For effective protection of the process transmitters, it is necessary to protect power supply and mA outputs by using overvoltage protection devices. We recommend: - Data Pro 2x1 24 V/24 V for potential-free (galvanically isolated) data lines, 25 A leakage current as well as automatic self-control by failsafe diodes, which interrupt the current signal in case of error and cause an error message, given out by the process transmitter. -

The structure of the menu systems for the process transmitters CIT 400 and CIT 401 is identical. The CIT 401 deviates from the other by the gray marked menus, which are not available with CIT 400. - Page 10 CIT 400 / CIT 401 Display mode (measured value is displayed) Password activation Menu PAoF Scaled measure- Parameters of the Input signal Input signal Output signal Scaled value Output signal ment values display in mA in % in % with offset and...

Page 11: Menu List
CIT 400 / CIT 401 5.5 Menu list Menu level diSP - parameter of the display (mode) The menus "dIS1" to "dIS6" determine the display mode. Display - scaled measurement value dIS1 Indicates the scaled measurement value on the display. The indicated value may vary between 0.000 and 9999. - Page 12 CIT 400 / CIT 401 Menu level SinP - parameter of signal input (analogue input) The subordinate menu items are used to define the measurement span of the analogue input for 4 mA and 20 mA. Signal input - starting point of measuring range...
- Page 13 This menu level can be called up by pressing Enter like any other menu. After that, the respective relay must be selected. This can be achieved by selecting the numbers of the relay with the arrow keys. Confirm your selection with Enter (CIT 400 features 2 relays; CIT 401 features 4 relays).
- Page 14 CIT 400 / CIT 401 Menu level Aout - analogue output The settings for the analogue signal output are determined in the menu items. Analogausgang - output signal outY This menu defines the output signal range. You can choose between the following settings: 4-20 mA, 0-20 mA, 20-4 mA and 20-0 mA.
- Page 15 By changing the relays, both pumps will be activated on reaching the next turn-on point. With CIT 400, this function can be switched on and off. With CIT 401, values 2, 3, 4, and OFF can be set. The value gives the number of used relays for the changing.

Page 20: Recalibration
CIT 400 / CIT 401 10. Recalibration During the life-time of the device, the offset may shift. As a consequence, a deviating signal val- ue in reference to the nominal pressure range starting point may be transmitted. The full scale may also shift. This would cause a signal value of the pressure switch to be transmitted that deviates from the nominal pressure range end point. -
