7 / 112 page ![]() E5GC 7 Alarm Types Each alarm can be independently set to one of the following 17 alarm types. The default is 2: Upper limit. (See note.) Auxiliary outputs are allocated to alarms. ON delays and OFF delays (0 to 999 s) can also be specified. Note: In the default settings for models with HB or HS alarms, alarm 1 is set to a heater alarm (HA) and the Alarm Type 1 parameter is not displayed. To use alarm 1, set the output assignment to alarm 1. Set value Alarm type Alarm output operation Description of function When alarm value X is positive When alarm value X is negative 0 Alarm function OFF Output OFF No alarm 1 Upper- and lower-limit *1 *2 Set the upward deviation in the set point for the alarm upper limit (H) and the lower deviation in the set point for the alarm lower limit (L). The alarm is ON when the PV is outside this deviation range. 2 (default) Upper-limit Set the upward deviation in the set point by setting the alarm value (X). The alarm is ON when the PV is higher than the SP by the deviation or more. 3 Lower-limit Set the downward deviation in the set point by setting the alarm value (X). The alarm is ON when the PV is lower than the SP by the deviation or more. 4 Upper- and lower-limit range *1 *3 Set the upward deviation in the set point for the alarm upper limit (H) and the lower deviation in the set point for the alarm lower limit (L). The alarm is ON when the PV is inside this de- viation range. 5 Upper- and lower-limit with standby sequence *1 *4 A standby sequence is added to the upper- and lower-limit alarm (1). *6 6 Upper-limit with standby sequence A standby sequence is added to the upper-limit alarm (2). *6 7 Lower-limit with standby sequence A standby sequence is added to the lower-limit alarm (3). *6 8 Absolute-value upper-lim- it The alarm will turn ON if the process value is larger than the alarm value (X) regardless of the set point. 9 Absolute-value lower-limit The alarm will turn ON if the process value is smaller than the alarm value (X) regardless of the set point. 10 Absolute-value upper-lim- it with standby sequence A standby sequence is added to the absolute-value upper- limit alarm (8). *6 11 Absolute-value lower-limit with standby sequence A standby sequence is added to the absolute-value lower- limit alarm (9). *6 12 LBA (alarm 1 type only) -*7 13 PV change rate alarm - *8 14 SP absolute-value upper-limit alarm This alarm type turns ON the alarm when the set point (SP) is higher than the alarm value (X). 15 SP absolute-value lower-limit alarm This alarm type turns ON the alarm when the set point (SP) is lower than the alarm value (X). 16 MV absolute-value upper-limit alarm *9 Standard Control Standard Control This alarm type turns ON the alarm when the manipulated variable (MV) is higher than the alarm value (X). Heating/Cooling Control (Heating MV) Heating/Cooling Control (Heating MV) Always ON 17 MV absolute-value lower-limit alarm *9 Standard Control Standard Control This alarm type turns ON the alarm when the manipulated variable (MV) is lower than the alarm value (X).
