5.4 PAS - Password.
Possible selections are 0... 999.
When the password is 040, changes can be made in all menu points.
When the password is <> 040, programming is blocked in all menu
points but open to reading of settings.

006 = Trip amplifier / window with an external setpoint:
Input A is connected to the process signal and input B is connected to
an external setpoint.
The relay trip function can be selected as TF = Increment, decrement,
or Window. If the trip function has been selected as 1.1 = InC, the UP
relay will be activated, when the input value (input A) is larger than the
external setpoint (input B).The relay will be de-activated again when
the input value is smaller than the setpoint minus the hysteresis. If the
function 1.1 = dEC has been selected, the UP relay will be activated
when the input value is smaller than the setpoint. The relay will be
de-activated again when the input value is larger than the setpoint plus
the hysteresis.
The neutral zone will offset the setpoint by the value entered in 1.3
nE1 and 1.4 nE2 - positive for increasing (TF = InC), and negative for
decreasing (TF = DEC) input value (input A). If you request the relays to
be activated at different input values, two different neutral zones must
be entered.
The same description applies to DOWN relay.
The two trip relays use the same external setpoint (input B).
Window:
When the input signal is within the setpoint ± the neutral zone, the relay
is inactive. The relay will be activated when the input signal exceeds the
setpoint ± the neutral zone.
When the input signal approaches the setpoint from a higher value, the
relay will be de-activated at the setpoint plus the neutral zone minus
the hysterersis.
When the input signal approaches the setpoint from a lower value, the
relay will be de-activated at the setpoint minus the neutral zone plus
the hysteresis.
This description applies to both UP and DOWN relay.
5.2 FrQ - Frequency.
Possible selections are 50 or 60 Hz.
Selection of common mode frequency suppression.
5.3 dSP - Default display.
Possible selections are the A / B input or output.
The display is the percentage of Full Span. For modules with a Pt100
input, also °C can be displayed.
