INDEPENDENT RELAY PROGRAMMING (P110 and P111)
These parameters need only be accessed if the Relay Set Up (P100) selected does
not exactly match the relay operation desired.
When any of the following Relay Parameters are accessed, the Point Type display
changes to the Relay Symbol and the Relay Number (corresponding to the HYDRO+
terminals) is displayed in the Point Number field.
The HYDRO+ provides almost infinite versatility in relay programming capabilities.
The following Relay Parameter descriptions are intended only for use to determine if a
feature is required for a specific application and to define the values or range of
values applicable.
For relay feature combination and interaction examples, see APPLICATIONS .
P110 RELAY ALLOCATION
This value may only be altered if Operation is set for
DPD
(Differential Level)
or
DPA
(Average Level). (P001 = 4 or 5).
As preset, all relay operation pertains to Point Number 1, unless
automatically altered by the Relay Set Up (P100) selection, if used.
Enter the Point Number(s) which the Relay Number (displayed)
operation is to be based upon.
e.g. To allocate Relay 3 to Point 1, with Relay Number 3 displayed, enter 1.)
If the relay is allocated to more than one Point Number (1,2, and / or 3),
any Point Number allocated can set the Relay Function (P111) "ON".
This value is reset if Relay Set Up (P100) is altered.
values: 1 = Point # 1 2 = Point # 2
1.2 = Point # 1 or 2 2.3 = Point # 2 or 3
1.3 = Point # 1, 2, or 3 3 = Point # 3
