4.2.2 If the lower display window alternately display “HIAL”, “LoAL”, “HdAL” or “LdAL”, it means high limit
alarm, low limit alarm, deviation high alarm, and deviation low alarm occurs. The alarm display can also be
turned off by setting parameter “cF”.
4.2.3. For program type instruments AI-518P, run is for common status. the lower display may alternately
display between SV and “StoP”, “HoLd”, or “rdy” which means the program control is stop, pause and ready.
There are 10 indication lights on the front pannel:
“PRG” on indicates program control status, flashing means that the program is in that status of hold or ready,
and off means the program stops.
Light “MAN” on means manual output status, and off means auto control status.
MIO, OP1, OP2, AL1, AL2, AU1 and AU2 respectiviely indicate I/O operation of the corresponding module.
For example, That the COMM indicator is lighting means that the instrument is communicating with
computer.
When current module X or X4 is installed on OUTP socket, the brightness of OP1 and OP2 indicates the
magnitude of the current. When K5 single phase shifting module is installed on OUTP sockets, OP2 on
indicates that the external power is on, and the brightness of OP1 shows the magnitude of phase-shifting
trigger output.
4.2 Operation Description
4.2.1 Display status switch
Depending on the instrument model, press
key can switch between different display status.
