Advanced settings menu
Password protection (PASS): Programming access can be blocked by assigning a password. The password is saved in the
device in order to ensure a high degree of protection against unauthorized modifications to the configuration. If the
configured password is not known, please contact PR electronics support - www.prelectronics.com/contact.
Memory (MEM): In the memory menu you can save the configuration of the device in the PR 4500 communication interface,
and then move the PR 4500 communication interface onto another device of the same type and download the configuration
in the new device.
Display setup (DISP): Here you can adjust the brightness contrast and the backlight. Setup of TAG numbers with 6
alphanumerics. Selection of functional readout in line 3 of the display - choose between readout of analog output or tag no.
Two-point process calibration (CAL): The device can be process-calibrated in 2 points to fit a given input signal. A low input
signal (not necessarily 0%) is applied and the actual value is entered via the PR 4500 communication interface. Then a high
signal (not necessarily 100%) is applied and the actual value is entered via the PR 4500 communication interface. If you
accept to use the calibration, the device will work according to this new adjustment. If you later reject this menu point or
choose another type of input signal the device will return to factory calibration. Process-calibration is cleared if you edit either
of the parameters: input type, input low, input high, display low or display high. Process calibration data are not saved to the
configuration repository of the PR 4500 communication interface.
Process simulation function (SIM): Simulation of process value is possible via the up and down arrows, thus controlling the
output signal. The point REL.SIM allows you to activate relay/-s by means of the arrow-keys up/down. You must exit the menu
by pressing 3 (no time-out). The simulation function exits automatically if the PR 4500 communication interface is detached.
Orientation setup (ORIEN): When the device is mounted upside down the display orientation of the the PR 4500
communication interfaces can be programmed to be rotated 180 degrees and reverse the up/down button functions.
Bluetooth communication (BLUE): (available for 4512 Bluetooth communication enabler). User-configurable Bluetooth
communication with the option to enable two-factor authentication. You can use Bluetooth communication with PR Process
Supervisor app.
Modbus setup (MODB): (available for 4511 Modbus communication enabler). With the Modbus RTU interface you can set
Modbus address, parity, stop bit, response delay and baud rate.
Latch function (LATC): The latch function can be applied for a relay when combined with the setpoint, windows or error
function. The latch function will hold the relay in its active/alarm state until latch is released via the PR 4500 display. If the
setpoint, window or error function demands an active relay you cannot release the latch.
If the configuration is copied from one device to another by way of the PR 4500 communication interface, the latch function
must be reconfigured.
