9 | Deviation upper-limit with standby sequence: This alarm output operates when PV value reaches set value (SV value) and the reached value is higher than the setting value SV+(AL-H). |
10 | Deviation lower-limit with standby sequence: This alarm output operates when PV value reaches the set value (SV value) and the reached value is lower than the setting value SV-(AL-L). |
11 | Hysteresis upper limit alarm output: this alarm output operates if PV value is higher than the setting value SV+(AL-H). This alarm output is OFF when PV value is lower than the setting value SV+(AL-L). |
12 | Hysteresis lower limit alarm output: this alarm output operates if PV value is lower than the setting value SV-(AL-H). This alarm output is OFF when PV value is higher than the setting value SV-(AL-L). |
13 | CT alarm output: This alarm operates when the current measured by transformer (CT) is lower than AL-L or higher than AL-H (This alarm output is available only for the controller with current transformer). You can set current alarm range between 0.5A ~ 30A, display resolution is 0.1A and measure accuracy is +/- 0.5A. |
