4 GIAN - Manual for connection and operation Version:. Page. Introduction Our compact indicator GIA N is a microprocessor controlled display, supervision and control unit for universal applications. There are connections for four standard signals ( to ma to ma, to Volt and to Volt), two temperature sensors (KTY- and Pt), frequency measuring and counter functions. In addition, two switching outputs are available, which can be configurated as two-level controller, three-level controller, two-level controller with min./max. alarm, common or individual min./max. alarm. Furthermore, the unit is equipped with a standard RS interface, thus allowing communication with a host computer. When leaving our factory the compact indicator has been subjected to various inspection tests and is completely calibrated. Before it can actually be used, the compact indicator will have to be configurated for customer's application.

8 GIAN - Manual for connection and operation Version:. Page.. Wiring of switching outputs Both switching outputs of the GIAN are designed as open collector transistor outputs. In the active mode the signal (switching output on) existing at the switching output will be switched reversely to the negative pole of the supply voltage (connection ). If an output is configurated for alarm, it will be 'on' as long as in idle state (no alarm). In case of an alarm condition being fulfilled, the output transistor will 'open'. Please note that the max. permissible voltage of Volt and the max. switching current of ma must not be exceeded (not even for a short time). Especially when switching inductive loads (e.g. relays, coils etc,) protective arrangements to limit voltage peaks have to be taken. When switching large capacitive loads the making current will have to be limited to the permissible amperage by connecting a series resistor or a current limiter. The same applies to incandescent lamps, whose making current is also quite high due to their low cold resistance. Relay Relay - VDC Voltage limitation with freewheeling diode (e.g. N) Connection of relay - - VDC Connection of audible piezo alarm and lamp k - VDC Uin semiconductor relay. Wiring of several GIAN Input and outputs of the GIAN as well as the RS interface are not electrically isolated. If several GIAN will be interconnected you have to make sure to avoid accidental energization. Make sure to observe the following points : Connection of a semiconductor relay If several GIAN are supplied by one supply voltage source, the sensors, measuring transducers etc. have to be electrically isolated. If the sensors, measuring transducers etc. cannot be electrically isolated, the GIAN will have to be operated with electrically isolated supply voltage sources. Please note, that an electric connection may also be created via the media to be measured (e.g. ph-electrode and conductivity electrode in liquid). If the GIAN units are connected via the RS interface, the sensors, measuring transducers etc. will have to be electrically isolated. If the compact indicators are supplied from one voltage source, the accidental energization (-Uv to -Uv) must not exceed Volt. GREISINGER electronic GmbH Hans-Sachs-Straße D- Regenstauf Telefax ()

The pulses received at the input will be divided by the scaler value before being evaluated by the GIAN. The GIAN is able to process a maximum number of pulses directly. By entering a corresponding scaler value pulse frequencies of up to pulses (= pulse/s *) can be displayed. The GIAN counter ranges from to pulses. By means of the scaler this range can be extended to up to pulses (*). Coarse scaling of the GIAN is also facilitated by the scaler value. Example: A flow sensor emits pulses per litre. By entering a scaler value of one pulse per litre will be transferred to the GIAN for evaluation. If possible, we recommend setting a scaler value above, as this will render the compact indicator unit more insensitive to high frequency interference signals.

Availability The RS interface cannot be used if the compact indicator is configurated as upwards or downwards counters. When used in connection with the frequency measuring function, the following limitations have to be taken into account: Any data exchange whatsoever at the RS input of the GIAN, will interrupt the frequency measuring. The display will continue to show the value measured last. In case of the data exchange lasting for some time, the display will show the fault code FE, thus signalling that frequency measuring has been interrupted. In order to allow frequency measuring and data communication to take place simultaneously, a break of at least s will have to be introduced between two data request/transfer.

27 GIAN - Manual for connection and operation Version:. Page. GIAN - digital display only The GIAN unit is equipped with the "no " and "no " functions. In this mode the GIAN is a display unit only, no measurements are taken. Please note that the "no " and/or "no " functions can only be activated via the RS - interface and cannot be set via the keys located at the unit... Digital display mode : In this mode the value transmitted via the interface is displayed. Please note: The display value and decimal point position will be transmitted separately (see data format and/or )... Digital display mode : This mode can be used to call up the display elements of the GIAN unit directly. In addition a blinking mode can be activated for each of the display elements individually. The segment information is transferred via the two F/F-Codes "" (H, H) and "" (H, H). As the GIAN works with ASCII-Codes only it is possible to transmit segment informations ( bit) per F/F-Code. To control the segments of the display two F/F-Codes are required. First of all send Code "" prior to sending Code "". Sending of "" freezes' the display value. By sending "" the value is made available for the display. Please refer to the opposite table for the segment assignment. In addition to controlling the individual segments the blinking mode can be activated for each of the four -segment displays. Use the F/F-Codes "" to activate and deactivate the blinking mode. By sending of "" the value will be made available for the display simultaneously.
