Adjustment elements
Integration time
An integration time t
i
of 0 … 10 s can be ad-
justed for damping of 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
• For every 1 s requested integration time,
push the “+“-key once
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 clear text
indication. The jump 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 the other within the menu.
Branching
A branching is indicated with the symbol ▼
and enables a jump to the below menu with
the “OK“-key. In this menu you can find pa-
rameters 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 pushing again, the
value is modified. The modified value can be
saved with the “OK“-key. Push the “
®“-key to
interrupt the input (without storing the modifi-
cation).
Certain parameters can only be indicated
and their values cannot be modified.
Reset
A reset is marked with the symbol ▲
and
enables with the “OK“-key a jump to the
above menu.
Automatic reset to measured value indication
is triggered 60 minutes after having pushed
a key for the last time.
