6.9.5 Fixed voltage Output Mode ( Sub-maintenance Mode )
External devices which receive voltage or output from the master unit can undergo zero or span
adjustment in this mode as required. Select a 0V output to x the voltage and current output to 0V
and 0 mA, respectively ( to 1V and 4mA if '1V to 5V' has been selected as the voltage output
range).
Select a 5V output to x the voltage and current outputs to 5V and 20 mA, respectively. Leaving
this mode allows the voltage and current output to return to the ordinary state where the voltage
and current output are proportional to the speed.
The operation procedure is shown in the gure on the following page.
At -5-A3, press the
F 1
key to select the
xed voltage output mode. The display then chang-
es to that marked a.
To select the 5V output press the
F 2
key while
the display is at a. The display then changes to that
marked b, and a xed voltage of 5V is output. If the
F 1
key is pressed while the display is at b, the
display returns to a and a xed voltage of 0V is
output.
6.10 Error Code Display Mode (Sub-maintenance Mode)
In this mode, LED error indications for the master unit in item (4) of Section 5.3 are as shown below:
LEDerrorindicationsonthemasterunit'sMDS1
ROM error
RAM error
Speed input error (sensor input error)
Communication error 1 (related to the master indicator) (*1)
Communication error 2 (related to GPS)
Voltage drop of memory backup battery
*1: Error information from the Master unit usually becomes “M-Err” in the LED display of the Master indicator, and it becomes “Err” only
for “communication error 1”
In the Error Code Display Mode, the screen in -4
appears.
Refer to item (4) of Section 5.3 for errors and error
codes.
