20mA analogue output displays 100 .
<3> ALARM-1
- Alarm-1 relay output (You can choose low or high by AL-TYPE setting)
<4> ALARM-2
- Alarm-2 relay output (You can choose low or high by AL-TYPE setting)
<5> AL-TYPE(ALARM-TYPE)
- Four kinds alarm choices: H&HH, H&L, L&H, L&LL
- Alarm relay: ALARM-1 and ALARM-2
ex) If you choose H&L,
ALARM-1: High alarm (it operates when measured value goes over the set value)
ALARM-2: Low alarm (it operates when measured value goes below set value)
<6> AL-RESET(ALARM RESET)
- Choose Alarm release methods.
- AUTO 
 
 MANUAL
(1) AUTO: Without touching RESET key, relay releases automatically when the
measured value goes out of alarm range.
(2) MANUAL: With touching RESET key, relay can be released when the measured
value goes out of alarm range.
<7> AL-TIME(ALARM TIME)
-
Set time of temporary external impact or noise which affects the sensor ’’’’ s normal operation.
The detector skips the sensor ’’’’ s temporary abnormal operation during this time.
<8> INITTIME(initialization time)
-
Set warming up time. Stable signal output is available after this time from power on.
<9> OFFSET
-
Set values to offset the measurement error.
ex) If you set OFFSET = -5,
If sensor output = +5, LCD displays 0 after offset by -5.
<10> ADDRESS
-
Set RS-485 address.
<11> BAUDRATE
- Set RS-485 baud rate.
