CONFIGURATION / OPERATING
THE FUNCTION KEYS
Documentation for the routing diagram
In general:
When configuring the display you are guided through all parameters, allowing
you to 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 way of the 3 function keys
will increase the numerical value or choose the next parameter.
decrease the numerical value or choose the previous parameter.
accept the chosen value and go 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 will return to the previous menu or go back to the
default state (1.0) without saving the changed values or parameters.
If no key is activated for 2 minutes, the display will return to the default state
(1.0) without saving the changed values or parameters.
Furhter explanations:
Fast setpoint adjustment and relay test: These menus are interactive and
allow you to adjust the setpoints while the display is measuring the input sig-
nal. The diodes will then indicate when the relays change state, thus easing
the setpoint adjustment in many situations. By activating
neously, a relay test will be initiated and the relay will change state. The set-
point adjustment will be saved by a quick press of
more that 0.5 seconds wil return the display to the default state (1.0) without
changing the setpoint.
Password protection: Using a password will block access to the menu and
parameters. There are two levels of password protection. Passwords be tween
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). Default password
2008 allows access to all configuration menus.

PROGRAMMING VIA PC

By way of PReset, a simple yet sophisticated PC program, all operational
parameters in the 5715 can be quickly configured to suit any application.
Furthermore, the PC configuration allows you to set up a customer-defined
input type for the input signals current, voltage and potentiometer. This input
type can be defined with special input spans, e.g. 5...12 mA, and customer-
defined linearisation with or without offset. The customer-defined input type
is saved in the 5715 in the input menu % - */. If the display is later configured
by way of the front keys for e.g. temperature input, the input type % - */ con-
taining all the original parameters can be subsequently selected. The PC con-
figuration is sent to the display by way of the communications interface USB
Loop Link.
