11. Prompt examinations for some parameters
Press [Fn] button to examine some parameters in normal working. Every time press
it, contents of one item will be displayed. If it keeps on some contents more than 6
seconds, it will return to normal working state automatically.
Content “1PXXXXX” is displayed first, it is comparative value of 1
＃
relay action.
And then content “2PXXXXX”is comparative value of 2
＃
relay action. “ALXXXXX”is
corresponding weight value of bottom of analog output, and “AHXXXXX” is
corresponding weight value of top of analog output.
12. Error indicating information
E1: overload of excitation loop or short circuit of load cell
E2: restriction for button operation, operating weight calibration under hardware
protection
E3: restriction for button operation, change mode of analog output under hardware
protection
E4: parameters are incorrect when calibrating, uV value of each division is less
than 0.6uV.
E5: restriction for button operation, adjust bottom and top of analog output under
hardware protection
13. Maintenance of indicator
13.1. Regular maintenance
Tiny maintenance is needed. In clean environment, maintenance for one time each
year is enough. But in dirty environment, times for maintenance should be
increased accordingly. Soft cloth can be used to clean the board. Any industrial
solvent and scour must not be used to spray indicator. Meanwhile, pay attention to
dust and water in daily use.
If interior circuitry board needs cleaning, power supply must be turn off. After that
open the outside box, and blow dust off from the board with dry high-pressure air.
13.2. Malfunction resolve
Phenomenon 1: Nothing is displayed after transducer is electrified.
Solution: 1. Check power supply
2. Check fuse
Phenomenon 2: Indicator displays “E1”
Solution: 1. Check load cell plug if it is short circuit
2. Check signal wire and junction box cable if they are damaged or
short circuit
Phenomenon 3: After Self Test, indicator displays “
―――――――
”all the time
Solution: 1. Check load cell plug if its connection is well
2. Check voltage if it is in the right range
