B. Setup menu, setting the limits of the instruments
The M3605 has 3 ways to change the limit values of the limit contacts. To make the handling of
the instrument simple, we have made a direct entry into the cursor menu available.
To enter the cursor menu below, you can either press the enter (ENT) key which leads you to
limit contact 1 directly. By pressing (ENT) again, limit contact 2 can be changed and so on until
limit contact 5.
By pressing (F1 to F4) you end up in the same menu, but directly on the desired limit contact.
Example: (F1) leads to limit contact 1, (F3) leads to limit contact 3 etc.
The third way, to set up the limit value is done by pressing the (ESC) key for more than 3
seconds. Then move with the arrow (+) / (-) keys to “Relay (Nr. of desired contact) settings”, press the
(ENT) key and move with the arrow (+) / (-) keys to “Rel (Nr. of desired contact): set point”. Then
press the (ENT) key again and change the limit value. Confirm with (ENT), skip with (ESC).
Quit the setup menu by pressing (ESC), or, wait a few seconds with no key operation. Values
can be altered with (+) and (-), or, depending on the menu, with the (F3) and (F4) as well.

Input range display
Min: Set the minimum point:
Example 1:
The instruments input signal:
0 … 20mA
Requested range: 4 … 18mA
Now set the Min to:
(4mA : 20mA * 100%) = 20%
Max:
Set the maximum point:
(18mA : 20mA * 100%) = 90%
Min: 20% & Max: 90% leads
to a new range of 4 … 18mA
Example 2:
The instruments input signal:
0 … 10V
Requested range:
2.5 …. 7.5V
Min = (2.5V : 10V * 100%) = 25%
Max = (7.5V : 10V * 100%) = 75%
→ 25% … 75% leads to 2.5 …
