Memo-Graph S 5 Operation / adjusting device settings - Set-up to commissioning
Endress+Hauser 37
Effect of the control input Only when used as control input:
triggers the allocated control function on the device when activated.
“only record”: the control input has no function, it is just recorded.
“External intermediate analysis”: as long as the control input is activated all active channels are analysed, i.e. the analysis
of min./max. averages is not made in cycles in fixed intervals / intermediate analyses, rather it is controlled via this digi-
tal input. The analysis starts when the input is activated. It is completed and saved when deactivated.
Example:
Acquiring minima, maxima, averages and quantities of a batch production.
# Warning!
Under “Signal analysis”, “Intermediate analysis” must be set to “external”.
“Lock set-up”: as long as the control input is activated, the “Set-up” key is not accessible. The set parameters can not be
displayed or changed until the control input deactivated again.
“Show text”: the specified text is shown in a message box, as long as the input is activated. If “Text, 1st part” and “Text,
2nd part” have been filled in, both parts are displayed together in the box.
Tip:
Use this, for example, as a brief procedure instruction for the operator on site.
“Display group”: the display switches to the selected group when the input is activated (signal leap from Low to High).
“Display dark”: as long as the input is activated, the display's back lighting is switched off. The device's remaining func-
tions (e.g. storage, limit value monitoring, etc.) are not affected by this.
“Synchronise time”: when the input is activated (signal leap from Low to High), the internal second counter is set to
zero. If the second indicator is between 0 and 29, the minutes remain unchanged. If the second indicator is between 30
and 59, the minutes are increased by one.
Tip:
Use this function in conjunction with a master clock. All devices used in this way run synchronously. Any signals measu-
red on different devices can be clearly compared with each other chronologically.
“Product Start/Stop”: indicates when the production of a previously selected product starts / stops. If product-specific
has been selected in “Basic settings - Operating modes - Limit values”, those limit values allocated to the selected product
are monitored as long as this digital input remains activated.
“Product selection (BCD)”: here the product is selected via a binary coded signal. For this, every digital input required
must be set to “Product selection (BCD)”. The lowest position is automatically allocated to the lowest free digital chan-
nel:
Digital input 1 = 20
Digital input 2 = 21
Digital input 3 = 2²
Digital input 4 = 2³
“Save text”: when the input is activated, a previously selected text ( see text selection (BCD) ) is saved.
“Text selection (BCD)”: here the text is selected via a binary coded signal.
“Save curve”: as long as this input is activated, the activated channels are also recorded under “Signal settings - Form
groups - Memory cycle”, i.e. the screen display and storage of the signal recording are controlled externally.
! Note!
• The limit value monitoring also functions when this input has not been activated.
• Use this function (input not activated), e.g. if you do not want to fill the memory with unnecessary / irrelevant measu-
rement data between batch productions or during system maintenance.
Advantage:
Better use of the internal memory and the ATA flash card, in which only really relevant information is recorded.
