P982 Rate
In automatic mode, the rate at which the level will move up and down is
determined by distance, P981 Increment and the time, P982 Rate which by
default is set to 1min and can be changed as required. To increase the rate
at which the level moves increase the Increment (P981) or decrease the
Rate (P982). To decrease the rate at which the level moves decrease the
Increment (P981) or increase the Rate (P982).
P983 Start Level
When using automatic simulation, this parameter can be used to pre-
determine the point at which the simulated level will start at and return to.
This can be used to simulate the lowest point to which the level would
normally operate.
P984 Inc. Change
When using automatic simulation, you can incrementally increase or
decrease the rate whilst running simulation. The rate is increased /decreased
incrementally by the value P984 (Incremental Change) by using the
“decimal point” key to increase and the “plus/minus” key to decrease the
rate of change. Default = 0.1m
Hardware
P990 Self-Test
If you enter 1 for this parameter, then the unit will perform a self-test. This
will confirm that the various parts of the circuitry are working correctly.
You will see confirmation messages that the clock and the EEPROM are
working correctly, and error messages for any parts that fail.
P991 Hard Test
When this parameter is selected, the unit will test the following in turn.
• LED’s. Watch them change colour as shown on the display, and
press, ENTER, if they operated as shown.
• Relays. Press a numeric key corresponding to the number of the
relay you wish to test, and the relay will change state each time the
key is pressed. If you press any other key, other than a valid relay
number, then the test will end.
• Segments. All the segments on the LCD are lit up, so you can see if
they all work. Press, ENTER, to end the test. The LED’s all go
green at the same time.
