External CubicleBUS Modules WL Circuit Breaker Short-circuit at 1: Only -Q1 establishes that a short-circuit has occurred and does not receive a blocking signal from a subordinate level. For this reason, it trips after t ZSI = 50 ms. Time saved = 250 ms. The ZSI function can be used for shortcircuits between the phases (S), with respect to ground (G), or for both simultaneously (S+G). The operating mode is set using the rotary switch. If the switch is in the “OFF” position, the ZSI is deactivated. The ZSI module also provides the blocking signal for medium-voltage level breakers. If a tie breaker is used in the power distribution system, this can also be equipped with the ZSI function and integrated in the overall concept. Up to 8 circuit breakers can be connected to ZSI IN, and up to 20 to ZSI OUT. Figure 2-14 2/31 The function of the ZSI module is selected using the rotary switch. Note: Proper performance cannot be guaranteed if these limits are exceeded. The ZSI module must always be the first external CubicleBUS module to be connected to the COM15/COM16 module or to X8. Test Function The outputs are set (i.e. a blocking signal is sent to other circuit breakers) when the rotary switch is set to “TEST.” Pressing the “TEST” key switches the ZSI module to test mode, which is indicated by the yellow DEVICE LED. The inputs and outputs are selected in the same way as the digital input/output modules. When the ZSI module input is selected, the input can be toggled internally by pressing and releasing the TEST key. When the outputs are selected, the outputs can be toggled by pressing and releasing the TEST key. This enables the circuit to be checked.

Active inputs and outputs are indicated by a yellow LED. It is recommended that the ZSI signal be transmitted via a shielded twisted pair with a cross-section of at least 0.75 mm 2 (18 AWG), and no more than 400 m long.
