G4 Multi Channel Force Instrument
6-7
‘Level X Up Delay’
Defines the Delay time for increasing signal. The level will switch when the supervised
value has been above Level X value during the set delay time. It is possible to use delay
and hystereses concurrently, but it is recommended to set the hystereses to zero when
the ‘Level X Up Delay’ is used.
‘Level X Down Delay’
Defines the Delay time for decreasing signal. The level will switch when the supervised
value has been below Level X value during the set delay time. It is possible to use delay
and hystereses concurrently, but it is recommended to set the hystereses to zero when
the ‘Level X Down Delay’ is used.
Level status
Actual status of the Levels (input signal above or below Level) can be read via
communication and shown at the display (the four first for each Function Block). The level
status includes the influence from hystereses and delays, but it does not show the status
of any digital outputs, connected to the Levels.
Use of inputs and outputs
Internal I/O’s are included on some of the I/O-modules that the G4 instrument can be
equipped with. Different module types have different number of inputs and outputs. A
DIO8 module have 8 inputs and 8 outputs while the force conversion modules
HS WF2, WF IN and WF IN2 each have 4 inputs and 2 outputs.
All input and output functions are controlled by set-up parameters in the instrument.
Digital inputs
The digital inputs can be used for remote operation of the instrument.
Digital outputs
The digital outputs can be used for control of external equipment and for indication of
instrument status.
Analog outputs
To produce analog outputs from the G4 instrument, a one channel AOUT1 or a four
channel AOUT4 module is used.
The analog output signal will represent a selected signal in the instrument in form of an
analog current or voltage signal. All analog output functions are defined by parameters
in sub menu ‘Analog outputs’, see chapter 4 ‘Set-up’.
