Memo-Graph S 5 Operation / adjusting device settings - Set-up to commissioning

Endress+Hauser 35

Signal settings: Digital inputs sub-menu (Option):

Note!

Settings only required if digital inputs (option - e.g. for counter / events) are to be used.

Hysteresis type “percentual %”: set hysteresis in %. “absolute”: specify hysteresis in the set process unit (e.g. in °C, bar, ...).

Hysteresis value The limit value status is not deactivated again until the signal is back to the normal range again by the value set here.

Time delay The signal must exceed or undershoot the specified value for at least the set time in order to be interpreted as a limit

value.

Alarm output Switches the corresponding relay in limit value status (or the open collector output). The terminal numbers are shown in

brackets. Please refer to the connection instructions (see “Safety instructions/type-related use” or “Connections/termi-

nal diagram”).

! Note!

• In case of a limit value, the relay is activated. For this, the relay contact is switched or closed at the factory (relay

1)/(relays 2-5) or the open collector is connected through.

• This operating mode can be inverted if required under “Digital outputs / Relays / OC”.

Alarm text on This text is (with date and time) shown on the screen if the limit value is violated and “LV messages” is set to “dis-

play+acknowledge”. Use this function, for example, as a brief procedure instruction for the operator on site.

Alarm text off Same as “Alarm text on”, but for returning from the limit value mode into normal operation.

Alarm messages “Display+acknowledge”: message on the display must be acknowledged by pressing the key (“OK”). It consists of the

date, time and channel identification with limit value (alternatively alarm text on/off, if a text has been entered there).

“Do not display”: limit value is displayed with a measuring point designation with red background.

Store limit value “Normal”: storage in normal memory cycle (setting under “Signal grouping - Memory cycle”).

“Alarm cycle”: memory cycle in case of limit value (setting under “Signal grouping- Alarm cycle”), e.g. in seconds.

! Note!
