17When HOLD status happens to PID program control, alarm output is ON.
18When STOP status happens to PID program control, alarm output is ON.
19When END status happens to PID program control, alarm output is ON.
¾To set Alarm Mode: Use the parameters 
, 
, 
in 【Initial Setting Mode】 to select the alarm mode. There are in total of 19 different modes (as listed in the table above).
¾To set Deviation Upper Limit of Alarm: Use the parameters 
, 
, 
in 【Operation Mode】to set the deviation upper limit.
¾To set Deviation Lower Limit of Alarm: Use the parameters 
, 
, 
in 【Operation Mode】 to set the deviation lower limit.
¾To set Alarm Delay Time(Unit: seconds): Use the parameters 
, 
, 
in 【Initial Setting Mode】 to set the alarm delay time.
¾To set Reverse Alarm: Use the parameters 
, 
, 
in【Initial Setting Mode】 to set the digit Y of value xxYx
(When Y=0: reverse, Y=1: forward)
¾To set Alarm 3: Alarm 3 function is available when an output board is connected to Output 2. Use the parameter 
in【Initial
Setting Mode】, press the key ▲ or ▼ to select for the following control output items: H1H2, C1H2… H1A2(H defines heating, C defines cooling, 1 indicates Output1, 2 indicates Output2 , A indicates Alarm3).
¾Select x1A2( set x to H or C) to operates Alarm3. To set Standby Alarm: Use the parameters 
, 
, 
in 【Initial
Setting Mode】 to set the digit Y of value xxxY (When Y=0: normal opeartion, Y=1: standby).
¾To set Hold Alarm: Use the parameters 
, 
, 
in【Initial Setting Mode】 to set the digit Y of value xYxx ( When
Y=0: normal operation, Y=1: Hold).
¾ To set Peak Alarm Signal: Use the parameters | , | , | in【Initial Setting Mode】 to set the digit Y of value Yxxx | |||
(when Y=0: normal operation, Y=1: peak signal). |
