If using a single output heater (Capacity: 200VAC, 1KW, 5A), normal heater current is 5A, and 
burnout heater current is 0A, the set value is calculated as (5A + 0A)/2 = 2.5A. Therefore, heater 
current values less than 2.5A will be deemed heater burnout and the alarm will activate. 
 
When two output heaters (Capacity: 200VAC, 1KW, 5A) are used, normal heater current is 10A 
(5A  ×2). If a single heater burns out, the heater current becomes 5A. The set value is calculated 
as (10A + 5A)/2 = 7.5A). Heater current values of less than 7.5A are deemed heater burnout and 
the alarm activates. 
6.4.10  Alarm output deactivation [PAR5 → DI-K→ AlRE] 
Available only if alarm output option is set to alarm latch or alarm latch and standby sequence1, 
alarm latch and standby sequence2. It can be set to turn OFF alarm output when alarm output is 
ON, alarm output conditions have been removed, or an alarm output deactivation signal that is 
greater than the minimal signal band is received. (However, alarm output deactivation is 
unavailable when alarm conditions remain in effect.) 
You can assign the front panel's digital input key or the digital input terminals (DI-1, DI-2) for the 
alarm output deactivation feature.(regardless of parameter mask) 
(1)  Deactivating alarm output using digital input key 
If the digital input key has been assigned for alarm output deactivation and the alarm output 
option is set to alarm latch or alarm latch and standby sequence, press and hold the front 
panel's    keys when alarm output is on. 
 
For detailed information on digital input key settings, see 6.7.4.2 Digital input key. 
(2)  Deactivation of alarm output using digital input (DI) terminal 
When the digital input (DI) terminal is assigned to alarm (output) OFF, the alarm output will 
deactivate when digital input (DI) terminal goes into the on state (close). (the MAN indicator 
turns ON).   
 
For detailed information on digital Input (DI) key configuration, see ‘6.7.4.2 Digital input key’.   
For detailed information on digital Input (DI) terminal configuration, see ‘6.7.4.1 
Digital input 
terminal settings [
PAR5 → DI-1/DI-2]’. 
After deactivating the alarm output, it will function normally for the next alarm output 
occurrence.
