4.6 Interfaces
In the INTERFACES submenu the CONTROL LOCATION, the RECORDER OUTPUTS, the
RS232 PROTOCOL, the PLC INPUTS, the PLC OUTPUTS and the BAUD RATE & END SIGN
can be edited.
4.6.1 Control location
The CONTROL LOCATION can be “LOCAL”, “RS232” or “LOCAL AND RS232”.
In
LOCAL mode the RS232 interface can only be used to read data, but not for control
purposes.
In RS232 mode, the Ecotec E3000 is controlled solely via the interface and the
display can only be used for viewing data.
In
LOCAL AND RS232 mode the Ecotec E3000 can be controlled via the interface but
also by input from the main display.
Default setting: local and
RS232
Notice: Even with the control location set to RS232 some parameter may still be
able to be changed through the main units software menus.
Please lock these by the menu PIN to prevent unintended changes.
4.6.2 Recorder outputs
For the recorder output the “RECORDER OUTPUT SCALE” and the “RECORDER OUTPUT
GAS
” can be selected.
The
RECORDER OUTPUT SCALE can either be linear or logarithmic. The output signal is
provided through channel 1 (pin 1 of the I/O port).
Which of the 4 gases is indicated here is defined through the menu line
RECORDER
OUTPUT
GAS.
Recorder output scale
Example:
The trigger level of the corresponding gas has been set to 3 g/a.
LIN The voltage range spans from 0 V to 10 V.
The leak rate which is output is normalized with respect to the trigger
level for the corresponding gas. The trigger level will correspond to an
output of 1 V. Higher and smaller leak rates may be output as a
voltage deviating by a corresponding factor with reference to the
trigger level.
leak rate = 0.3 g/a U
analog
= 0.1V
leak rate = 3 g/a U
analog
= 1.0V
leak rate = 10 g/a U
analog
= 3.3V
Voltages over 1V indicate that the trigger level has been exceeded.
