Adjustment elements
Integration time
An integration time t
i
of 0 … 10 s can be ad-
justed for damping pressure shocks.
Procedure
• Set rotating switch to t
i
• By pushing the “-“-key 10-times, ensure
first of all that the integration time is set to
0 s
• Push the “+“-key once for every 1 s inte-
gration time required
The integration time is the time required by
the current output signal to reach 90 % of the
actual level after a step change of the proc-
ess pressure.
4.2 Menu-guided adjustment with
additional functions
The adjustment with the multiple function
module is menu orientated and is made via
the four keys in conjunction with the text
display. The move from the measured value
indication to the main menu is made with the
“OK“-key. Use the “®“-key to change from
one menu point to an other within the menu.
Branches
A branching is shown by the ▼ symbol and
enables a jump to the menu below with the
“OK“-key. In this menu you can find param-
eters which are linked (possibly in other
submenus).
Parameters have no ▲ or ▼symbol. The
value of the parameters can be modified with
the “+“ and “–“-keys or chosen from the list.
When these buttons are pushed once, the
value flashes first. When pushed again, the
value is modified. The modified value can be
saved with the “OK“-key. Push the “®“-key to
interrupt input (without storing the modifica-
tion).
Certain parameters can only be indicated
and their values cannot be modified.
Reset
A reset is shown by the ▲ symbol and ena-
bles a jump to the menu above with the “OK“-
key.
Automatic reset to measured value indication
is triggered 60 minutes after having last
pushed a key.
