In addition to measuring properties, the inputs perform predefined functions such as ignition control,
hour meter, the input for arming and disarming and so on. A detailed description of the functions is given below.
The inputs can be used both to obtain the values from the connected sensors and to take logical values
for further use in the processing of events, reactions of the security mode and to perform logic functions defining
the position of the ignition switch, running engine and so on.
TYPE OF INPUT
– the selected input operation mode is determined:
[not used]
– The input is not used.
[Analog]
– is an analog input with a measurement range from 0 to 36 V. If it is necessary to transfer the
measured value to the server, in the packet structure in the block "Inputs/Outputs (data)," check the box next to
the appropriate input (voltage of input 1 ... 8). Inputs 9-12 do not perform the measurement function; only a
discrete value is available for them. To obtain the discrete input status (active/passive) in the packet structure in
the block "Input/Output (status)," check the box next to "Discrete status of input 1-8." If outputs 1-4 have been
transferred to the INPUT state, to obtain the status on inputs 9-12 in the package structure in the block select
"Input / Output (status)," check the box next to "Discrete state of OUTPUTS/INPUTS
."
[
Frequency
]
- This input is used to measure the frequency of the signal (square wave). In most cases,
it is used to connect the frequency fuel level sensor. To transmit the value to the server in the packet structure
in the block "
Input/Output
(data)," check the box next to the appropriate input (Frequency Input 1 ... 8). For
correct calculation of the frequency, set the slider of the lower limit at the level of half the input signal
amplitude.
[
discrete
]
- To connect digital sensors with two work position "ON" or "OFF". For example, an alarm
button, closing the input to the supply voltage. The "HIGH" active layer is used, and it is recommended to set
the upper limit at 6-10V. The input status is transmitted in the block "Inputs/Outputs (Status)" - "Discrete status
of inputs 1-8" and "discrete status of Outputs/Inputs"
[
Counter
] - The input is used as pulse counters for operation composed of flow-through pulse sensors.
To transmit the value to the server in the packet structure in the block "
Input/Output
(data)," check the box next
to the appropriate input (Frequency Input 1 ... 8). The counter value is increased when the input changes to the
active state.
For all input types the triggering threshold in the active zone available.
Triggering threshold is selected by engines in multiples of 0.1V. The activity area of the input is shown
in red. To change the activity area, click the left mouse button on the desired area. The current value of the
input voltage is specified at the beginning of the scale. Activity area can take the following ranges:
1. Below the lower – the input is considered active if its voltage value is less than the voltage of the
left engine. Within the rest voltage range, the input state is considered not inactive.
2. Average - the input is considered active if the voltage on it is over the left engine voltage, and less
than the right engine voltage. Within the rest voltage ranges the input state is considered not inactive
3. Above the upper – the input is considered active if the voltage on it is greater than the right engine
voltage. Within the rest voltage range, the input state is considered not inactive.
