20 4116V105-UK
Latch
When the setpoint is exceeded the relay outputs enters an alarm state. The latch function of the 4116 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
1
and
2
to navigate in the menu and
3
to 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. 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 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 control the output signal up or down. 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.
