Configuration / operating the function keys
Documentation for routing diagram.
In general
When configuring the 4131, 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 line 3 on the display.
Configuration is carried out by use of the 3 function keys:
1will increase the numerical value or choose the next parameter
2will decrease the numerical value or choose the previous parameter
3will save the chosen value and proceed to the next menu
When configuration is completed, the display will return to the default state 1.0. Pressing and holding 3will return to the
previous menu or return to the default state (1.0) without saving the changed values or parameters.
If no key is activated for 1 minute, the display will return to the default state (1.0) without saving the changed values or
parameters.
Further explanations
Fast setpoint adjustment and relay test: These menus allow you to make a quick setpoint change and relay test when the
FastSet menu is activated. This function can only be activated when the relays are set for setpoint function and are controlled
by a setpoint.
Pressing 1and 2simultaneously will activate a relay test and change the state of the relay.
Pressing 3will save the setpoint change.
Holding down 3for more than 1 second will return the unit to the default state without saving the setpoint change.
Password protection: 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.
Signal and sensor error info via display front 45xx
Sensor error (see limits in the table) is displayed as SE.BR (sensor break) or SE.SH (sensor short). Signals outside the selected
range (not sensor error, see table for limits) are displayed as IN.LO indicating low input signal or IN.HI indicating high input
signal. The error indication is displayed in line 3 as text and at the same time the backlight flashes. Line 4 of the display is a
status line which displays status of relay 1 and relay 2, COM (flashing bullet) indicating correct functioning of 45xx and arrow
up/down which indicates tendency readout of the input signal. If the figure 1 or figure 2 flashes, the unit has detected that
the setpoint has been exceeded and that the relay is in “delay” mode. When the delay time has passed and the relay makes /
breakes, the relay sign either displays or disappears.
Signal and sensor error indication without display front
Status of the unit can also be read from the green LED in the front of the device.
Green flashing LED 13 Hz indicates normal operation.
Green flashing LED 1 Hz indicates sensor error.
Steady green LED indicates internal error.
Relay functions
6 different settings of relay function can be selected.
Setpoint: The unit works as a single limit switch
Window: The relay has a window that is defined by a low and a high setpoint. On both sides of the window the
relay has the same status.
Error function: The relay is activated by sensor error.
Power: The relay is activated as long as the power is on.
Off: The relay is deactivated.
Latch: The relay is latched. Only valid for setpoint and window function.
Increasing/decreasing: The relays can be set to activate at increasing or decreasing input signal.
Delay: An ON and an OFF delay can be set on both relays in the range 0...3600 s.
Hysteresis: 0.0...100.0%.

Latch
When the setpoint is exceeded the relay outputs enters an alarm state. The latch function of the 4131 will hold the relays in
this state until the function is deactivated manually. The latch function can be applied when the relay function setpoint or
window is selected.
The latch function can be selected separately for each relay output. If the configuration is copied from one device to another
by way of the 45xx, the latch function must be reconfigured.
The latch function activates and holds the relays when the input signal rises above or falls below the selected setpoints and
the relay action has been selected as increasing or decreasing.
The window function is selected by choosing ”window” in the menu and defining a high and a low setpoint.
It can be selected for each relay contact whether the contact is open or closed inside the window. This selection is made in
the menu R1.cont and R2.cont.
The setpoint function is selected by choosing ”setpoint” in the menu and entering the desired limit. The device then works as
a single limit switch.
An activated relay means that the contact is closed if the contact function ”normally open” is selected, and the contact is open
if the contact function ”normally closed” is selected.
The delay time for activation and deactivation can be set independently of each other in the menus ON.DEL and OFF DEL
respectively.
If the relay function ”Error” is active, the relay will latch when a sensor error occurs and will not be deactivated automatically
when the sensor error is rectified.
The relay can only be deactivated by an operator and only when the normal conditions for deactivation are met. If the input
signal still has a value that will activate the relay, the relay will latch again.
See the graphic depiction of the setpoint and window functions on pages 30 and 31.
Manual deactivation of the latch function
If the relay outputs are activated and thereby latched, it will be indicated in the display. The backlight flashes and the scrolling
help text tells you how to deactivate the output. Manual deactivation is carried out by way of the front buttons on the 45x.
Use 1and 2to navigate in the menu and 3to validate your selection. If the password protection has been activated, the
password must be entered in order to access the deactivation menu. See the menu structure on page 27.
Advanced functions
The unit gives access to a number of advanced functions which can be reached by answering “Yes” to the point “ADV.SET”.
Memory (MEM): In the memory menu you can save the configuration of the device in the 45xx, and then move the 45xx 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. Line 3 of the display shows 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 45xx. Then a high signal (not necessarily 100%) is
applied and the actual value is entered via 45xx. 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 simulation function (SIM): In the menu point “EN.SIM” it is possible to simulate an input signal by means of the arrow
keys and thus test the function of the relays. You must exit the menu by pressing 3(no time-out).
The following point allows you to activate relay 1 and relay 2 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 45xx is detached.
