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 unauthorised modifications to the setup. Default
password 2008 allows access to all setup modules.
Signal and sensor error info via 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 red LED indicates internal error.
