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: Staff Qualification
CIT 400 1.2 Staff qualification Qualified persons are persons that are familiar with the mounting, installation, putting into ser- vice, operation, maintenance, removal from service, and disposal of the product and have the appropriate qualification for their activity. This includes persons that meet at least one of the following three requirements: They know the safety concepts of metrology and automation technology and are familiar therewith as project staff. -
Page 5: Safe Handling
CIT 400 1.5 Safe Handling NOTE - Treat the device with care both in the packed and unpacked condition! NOTE - The device must not be altered or modified in any way. NOTE - Do not throw or drop the device! NOTE - Excessive dust accumulation (over 5 mm) and complete coverage with dust must be prevented! NOTE - The device is state-of-the-art and is operationally reliable. -

CIT 400 3. Mounting 3.1 Mounting and safety instructions Danger of death from explosion and electric shock Always mount the device in a depressurized and de-energized condition! DANGER Do not install the device while there is a risk of explosion. Danger of death from improper installation Installation must be performed only by appropriately qualified persons DANGER... -
Page 7: Electrical Installation
CIT 400 3.4 Electrical installation For installation the lawful regulations of the respective country have to be observed. The power supply must be separately protected by a 6 A slow-blow fuse and has to be iso- lated from other facility parts (separate turn-off, e. g. by using an automatic cut-out with >B<... -
Page 8: Installation Example
CIT 400 3.5 Installation example The power supply of the transmitter has principally not been drawn, but is mandatory. The ex- amples listed below represent only a selection of possible combinations of the sensor CIT 400. Example 1: CIT 400 with analogue output, supplied by a 2-wire-sensor; with alarm relay Limit value message Rel. -

The grounding (earth) must lead to the unprotected side. -
Page 10: Menu Operation
CIT 400 5.2 Menu operation The menu system is a closed system allowing you to scroll both forward and backward through the individual set-up menus to navigate to the desired setting item. To leave a menu item, push the Enter-button. To leave the menu system completely, the last menu item has to be scrolled over or you will have to wait until the device changes automatically to display mode (about 1 minute after pushing a button). - Page 11 CIT 400 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 in mA Menu diS1 Menu diSP Menu diS2...

Page 12: 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 13 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 The measurement value for the analogue input at 4 mA must be entered ZPIn here.
- Page 14 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 15 CIT 400 Menu level Aout - analogue output The settings for the analogue signal output are determined in the menu items. Analogue output - output signal This menu defines the output signal range. You can choose between outY the following settings: 4-20 mA, 0-20 mA, 20-4 mA and 20-0 mA. Se- lect by using the arrow keys and confirm with Enter.
- Page 16 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).

CIT 400 6. Troubleshooting Danger of death from electric shock or from explosion If malfunctions cannot be resolved, put the device out of service (proceed according to chapter 9 up to 11) DANGER As a matter of principle, work on energized parts, except for intrinsically safe circuits, is prohibited while there is an explosion hazard. -
