Configuration / operating the function keys
Documentation for routing diagram.
In general
When configuring the 5725, you will be guided through all parameters and you can choose the settings which fit the
application. For each menu there is a scrolling help text which is automatically shown in the display if no key has been
activated for appr. 5 seconds.
Configuration is carried out by use of the 3 function keys:
1
will increase the numerical value or choose the next parameter
2
will decrease the numerical value or choose the previous parameter
3
will save the chosen value and proceed to the next menu
If a function does not exist in the hardware, all parametres belonging to that function will be skipped in order to make
configuration as simple as possible. The configuration will not be saved until the end of the menu structure when the display
shows - - - -.
Pressing and holding
3
will return to the previous menu or return to the default state ("Monitor") without saving the changed
values or parameters.
If no key is activated for 2 minutes, the display will return to the default state ("Monitor") without saving the changed values
or parameters.
Further explanations
Fast setpoint adjustment and relay test (only 5725D)
These menus are interactive and allow you to adjust the setpoints while the display is measuring the input signal. The front
LEDs will then indicate when the relays change state, thus easing the setpoint adjustment in many situations. By activating
1
and
2
simultaneously, a relay test will be initiated and the relay will change state. The setpoint adjustment will be saved by a
quick press of
3
. Holding down
3
for more that 0.5 seconds will return the display to the default state (”Monitor”) without
changing the setpoint.
Password protection
Using a password will block access to the menu and parameters.
If the configured password is not known, please contact PR electronics support -
5725D only:
There are two levels of password protection.
Passwords between 0000 and 4999 allow access to the fast setpoint adjustment and relay test menus (using this password
blocks access to all other parts of the menu).
Passwords between 5000 and 9999 block access to all parts of the menu, fast setpoint and relay test (current setpoint is still
shown).
Additional features (from s/n > 121435001)
Out of range indication at f/I function
Out of range min. limit is < 0.0009 Hz / (18 min. 31 sec.).
- if the In.Lo value is set to ”0.0” Hz the display readout will be ”0.0” when the ”out of range” min. limit is reached.
- if the In.Lo value is set different from ”0.0” Hz the display readout will be ”In.Lo” - flashing - when the ”out of range” min.
limit is reached.
Low cut-off filter
The 5725 frequency indicator has a selectable low cut-off filter, which sets the display and output to 0% when the measured
frequency is ≤ 0.5 Hz (2 s). This filter allows the display to ignore extremely low frequencies from flowmeters and encoders
which are sometimes present when the process is at idle.
Faster analog output
The analog output response time can be adjusted to a fast 0.1 second, allowing the analog output to track faster changing
input signals.
