11.1 Setting Alarm Type
Description
These alarms work irrespective of the operation mode.
The alarm-related parameters consist of the alarm type (type, stand-by action, energized/
de-energized, and latch function), PV velocity alarm time setpoint, alarm hysteresis,
alarm (On-/Off-) delay timer, and alarm setpoint.
In Cascade control, both of Loop 1 and Loop 2 have these parameters.
Alarm-related parameter Number of settings
Alarm type 8 (number of settings) x 2 (number of loops)
PV velocity alarm time setpoint 8 (number of settings) x 2 (number of loops)
Alarm hysteresis 8 (number of settings) x 2 (number of loops)
Alarm (on-/off-) delay timer 8 (number of settings) x 2 (number of loops)
Alarm setpoint 8 (number of settings) x 2 (number of loops)
► Alarm hysteresis: 11.3 Setting Hysteresis to Alarm Operation
► Alarm delay timer: 11.4 Delaying Alarm Output (Alarm Delay Timer)
► Alarm setpoint: 6.4 Setting Alarm Setpoint
Both of Loop-1 and Loop-2 have eight groups of alarms.
Factory default: Only four groups of alarm-related parameters are displayed.
► Terminal function: 17.4.7 Contact Output Wiring
Alarm output can be assigned to the unused control relay output or contact output.
► Control relay output: 11.5 Setting Alarm Output to Control Relay Terminal
► Contact output: 12.2.1 Setting Function of Contact Output
Energized/de-energized of alarm output can be changed.
► Energized/de-energized: 12.2.2 Changing Contact Type of Contact Output
To read the conditions of alarms, outputs, or latches via communication, see
Communication Interface User's Manual.
