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.
