Page 3: General And Safety-Related Information On This Operating Manual
CIT 400 1. General and safety-related information on this operating manual This operating manual enables safe and proper handling of the product, and forms part of the device. It should be kept in close proximity to the place of use, accessible for staff members at any time. -
Page 4: Intended Use
CIT 400 1.3 Intended use The multifunctional process transmitter CIT 400 has been especially developed for the supply and data acquisition of 2- and 3-wire-sensors with current signal. The micro-controlled device collect the signal of the sensor and show the measured value in a 4-digit LED-display. For sim- ple handling, the device features an extensive menu system with several menu levels. -
Page 5: Product Identification
CIT 400 2. Product identification The device can be identified by its type plate. It provides the most important data. By the order- ing code, the product can be clearly identified. For identification of the firmware, the program version (e. g. P074) will appear for about 1 second in the display after starting up the device. -

Page 9: Overvoltage Protection
CIT 400 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. -

Page 13: Menu List
CIT 400 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 Indicates the scaled measurement value on the display. The indicated dIS1 value may vary between 0.000 and 9999. Confirm with Enter after select- ing "dIS1"... - Page 14 CIT 400 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 15 CIT 400 Menu level rELn - parameter of the contacts (relais) The menu items of this level are responsible for the limit value settings and the switching behav- iour of the relays. Since the menus for the relays have been conceived identically, the descrip- tion is the same for all menus.
- Page 16 CIT 400 Contacts - switch-off delay With this menu, you can define a switch-off delay within a range from 0 D1of to 100 seconds for the selected relay. Set the delay with the arrow keys D2of and confirm with Enter.
- Page 17 CIT 400 Menu level ALLG - unit parameter Menu level contains general unit parameters. Unit parameter - relay exchange With this menu, you can set the exchange of used relays if they reach a CHAn defined value. The background of this function is a pump exchange in order to achieve a regular pump load (capacity utilisation).
