6.5.4 Change Alarm Types Of Dry Contacts
As one of the alarm type parameter, ‘Related Relay’ refers to the serial No. of the dry contract corresponding to the
alarm type, whose value is either 1 ~ 8 or ‘None’. ‘None’ means there is no corresponding dry contact. For details,
see 6.7.2Alarm Settings.
6.5.5 Programmable Setting On The Dry Contact Output Alarm Type
The PLC control is configure d by the background tool software.
The configuration method for the control function of the PLC is as follows: D＝A (Status) * B (Status) * C (Status)
D: Indicates the serial number of the dry contact corresponding to the output. Dry contacts 1~8 are available for
selection.
A, B, C: indicate the input alarm type. Status is for judging whether the alarm has occurred.
*: indicates the logic relation between two types of alarms. ‘and/ or’ may be selected.
The alarm types available for selection are shown in the following table:
Alarm type Alarm type Alarm type
