Outputs
The S2000-KPB provides control for connected executive devices by switching power voltage
from the unit’s terminals U
main
and U
back
to the terminals of the outputs. Connecting external power
supplies is prohibited and can damage the unit.
The S2000-KPB provides switching on (switching off, pulsing) for its outputs in accordance with
assigned control programs on receiving control commands over the RS-485 interface. The unit also
provides monitoring executive outputs and the monitored circuits connected to the outputs.
The available programs for executive outputs are shown in Table 2.

Note:
The full list of output executive commands can be seen in the User’s Manual for an
S2000M panel. When the S2000-KPB is connected to the internal interface RS-485-2 of an S2000-
ASPT unit, the first one is used to expand the discharge circuits of the last one. In this case the
individual outputs of the unit cannot be controlled remotely from the S2000M panel.
The output executive commands can comprise the Control Delay parameter. In such case the
program starts running after expiration of the specified time period. The Control Delay parameter
ranges from 0 to 8192 s (2 hours 16 minutes 32 s) in increments of 0.125 s. If Control Delay is missed
or equal to zero, the program starts running just after receiving the command.
Output control commands with the programs #5, #6, #7, and #8 (Switch ON/OFF) can include
detailed data defining a rate and pulse ration of switching the outputs. If these data are missed in a
command, the output will be switched on and off with 1 Hz frequency and pulse ratio of 2.
Output control commands with the programs #3, #4, #7, #8 («Switch for a Given Time») contain
the Control Time parameter. The Control Time can have a value from 0 to 8192 s (2 hours 16 minutes
and 32 s) in the increments of 0.125 s.
If Control Time is missed in a command then the program will be executed within the time given
in the unit’s configuration parameter Discharge Time.
If Control Time in a command is equal to zero, the output will be switched to the initial status for
the received command.
In case of an output control command with the program #11 the unit generates a discharge pulse
for the relevant output (the output is switched on for a given time and then the output is switched off).
If the command contains zero as the number of output, a discharge pulse will be generated for all
outputs one-by-one.
If a command contains no Control Time or no Control Delay, the values for them will be taken
from the unit’s configuration.
The value of discharge interval time is given by the relevant configuration parameter.
The unit provides monitoring of lines of connection of executive devices (the monitored circuits)
provided that termination elements - load connection modules are brought into the lines. The load
connection modules are installed inside the executive device enclosures (except for the release circuit).
