12.10.3 "PSCI" Input
The "Power Status Coordination Input" PSCI ("I/O" connection, pin 12) enables the
ES820.1/ ES830.1 module to be switched on automatically when the ignition is
switched on (Kl.15) and the module to be switched off automatically when the igni
-
tion is switched off (Kl.15).
To do this, the "PSCI" input is connected to the corresponding signal of the vehicle
electrical system. The function of the "PSCI" input can be configured. The switch-
off of the ES820.1/ ES830.1 module can be delayed in order to prevent a shutdown
and restart of the module if the ignition is only switched off briefly.
12.10.4 "In 1-4" Inputs
The statuses of inputs "In 1-4" can be recorded together with other signals or used
as a trigger for starting and ending the recording. The signals can also be used to
change the measurement configuration or to start data transmissions.
12.10.5 "Operation" Output
The "Operation" output signals the operating state of the ES820.1/ ES830.1 mod-
ule. The output can be used to automatically switch on the operating voltage of
other modules (e.g. additional measuring instruments) with the ES820.1/ ES830.1
module. The signal level is "High" whenever the ES820.1/ ES830.1 module is in the
"On" operating state. Otherwise, the signal level is "Low". A corresponding switch
-
ing device (relay, solid state relay) is required in order to switch the supply voltage
of a further measuring instrument.
12.10.6 LEDs Outputs
The "LEDs" outputs enable the operating state of the ES820.1/ ES830.1 module to
be displayed remotely (e.g. in the passenger cell). The LEDs are connected to
ground. The series resistors are already integrated in the device.
12.10.7 "Out 1-4" Outputs
Outputs "Out 1-4" can be used universally for display or control tasks. The outputs
are controlled by the software.
12.10.8 "Signal Generator" Output
The "Signal Generator" output enables remote signaling (e.g. in the passenger
cell). The signal generator is connected to ground.
NOTE
The inputs and outputs of the "I/O" interface are protected against surge volt-
ages and short-circuits.
NOTICE
Damage to the electronics
ES820.1, ES830.1: The ground contacts of the "I/O" interface must not be con-
nected to the vehicle ground.
