14.3 Signal- and sensor error info via display front UMU-FD
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 UMU-FD 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.
14.4 Signal- and Sensor error indication without display front
Status of the unit can also be read from the red / 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 red LED indicates internal error.
14.5 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 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 relay can be set to activate at increasing or decreasing
Input signal.
Delay:
An ON and an OFF delay can be set on both relay s in the range 0…3600 s.
Hysteresis:
0,0...100,0%.
