25 AUTOMATIC STANDBY UNIT MODI ZA for the circuit breakers Modeion and Arion WL DESCRIPTION Application The automatic standby unit (hereinafter referred to as ZA) is used to provide power supply without any longterm blackouts in various sectors of services, industry, etc. Function The automatic standby unit ensures automatic and, above all, safe control of switching of two power supplies to two loads sothat the electric poweris supplied without longfailures. The automatic standby unit is designed for collaboration with circuit breakers/switch-disconnectors Modeion and Arion WL, which ensure power switching. For detailed information on circuit breaker/switch-disconnector fitting see page 10. The power supplies can be switched over by a failure of one or more phases, undervoltage or overvoltage of the power supplies. The automatic standby unit enables the control (switching on/off) of the backuppowersupply (generator). Design in switchboard IP65 Advantages: The display of the automatic standby unit informs the operator of the immediate state of circuit breakers, power supplies and actually performed action. The automatic standby unit is protected against unauthorized resetting by the password. Safety The circuit breakers/switch-disconnectors are electrically interlocked by means of the automatic standby unit so that in no case both the power supplies can be switched on simultaneously. To increase safety in manual control it is possible to complete the circuit breakers/switch-disconnectors by mechanical interlocking. Power supply The automatic standby unit must be supplied either from controlled power supplies (or from a momentarily active one) or from an independent external power supply such as UPS or AKU. The function of the automatic standby unit depends in some cases on the power supply Metod (see time diagrams on page 17-19). Control and setting Basic functions of the automatic standby unit are selected by a rotary switch on the front panel, and additional settings (modes and reaction times) are set by means of control panel. Description On the front panel there is: a)adisplay informing the operator about immediate state of circuit breakers, power supplies and actually performed action. b)touch display for setting the parameters for automatic control of the standby mode. Example: reaction times (for detailed information see Table of Specifications on page 10), automatic standby mode (see functions and setting on page 15-16) or security password, which protects the automatic standby unit against unauthorized resetting. c)rotary switch for setting of 4 basic functions of the automatic standby unit(for detailed description see "functions and setting" on page 15 and 16). The built-in design on the switchboard door In the automatic standby unit: a)the user can use undervoltage relays (only for design ZA-xx-xx1x) to set the values of undervoltage or overvoltage (independently of each other) to be evaluated by the automatic standby unit as a power supply failure with taking an appropriate action. b)there is a screw terminal block for connection of individual conductors, which connect the automatic unit with circuit breakers/switch-disconnectors. c) Every automatic standby unit includes terminals for connection of the STOPbutton (terminals 30 and 31). Basic block diagram d) Every automatic standby unit includes terminals for connection of the inspection button (terminals 40 and 41). The inspection button serves for possible checks on instruments. If no mechanical interlocking is installed, it is necessary to beware of a parallel run. The inspection button will disable the control unit operation and will supply power to the under-voltage releases, see the wiring diagram. If the sheet-steel cover is used, the inspection button is already included and is connected. Touch display Two basic designs Automatic standby unit is delivered: a) In metallic switchboard design IP65. b)i n built-in design in the switchboard door. 3 The arrangement of circuit breakers/switch-disconnectors and their connection to the automatic standby unit The arrangement of circuit breakers (a distance between them) is not limited in any way. If mechanical interlocking is used to increase safety in manual control, the distance between the circuit breakers/switch-disconnectors is given by the used mechanical interlocking.

38 AUTOMATIC STANDBY UNIT MODI ZA for the circuit breakers Modeion and Arion WL FUNCTION, SETTING Setting of undervoltage relays (o nly design ZA-xx-xx1x) The automatic standby unit monitors the level of voltage of power supplies, power failures and phase sequence by means of undervoltage relays. On these relays it is possible to set the overvoltage / undervoltage level, to which the automatic standby unit shall react within the range + 30 % / -20 %; in case of ensuring permanent power nd supply of the system from 2 or standby power supply, it is possible to set the tolerance of the monitored voltage at +/- 30 %. Delay of making of the undervoltage relay contact is set by the manufacturer and cannot be changed.
