P*984 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  P*984  (Incremental  Change)  by  using  the 
“decimal point” key to increase and the “plus/minus” key to decrease the 
rate of change.    Default = 0.328 feet 
Hardware 
P1 or P2 
P*990 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. 
P*991 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. 
  Keys.  You  should  press  each  key,  to  confirm  it  works,  with  a 
counter showing how many more keys you have to press. Be sure 
to press the CANCEL key last, as this will show if all keys were 
pressed or not. If they were not, then an error message is displayed. 
P*992 mA Out Test 
This parameter will allow you to select either mA Output 1 or mA Output 2 
and force a specified current on to the output in order to test the equipment 
that  it  is  connected  to  the  output  and  to  make  sure  the  unit  is  working 
correctly. The figure you enter will be generated by the mA output.
