Signal and sensor error info via display front PGMMOD00
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 PGMMOD00 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 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 green LED indicates internal error.
Steady red LED indicates fatal 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%.
