DDB no. English text Source Description
1609 AR Enable CB1
External input via DDB mapped in PSL to
enable CB1, if "in service", to be initiated for
autoreclosing by an AR initiation signal from
protection. DDB input defaults to high if not
mapped in PSL, so CB1 AR initiation is
permitted.

1.8 Factory default programmable scheme logic
The following section details the default settings of the PSL.
The P54xmodel options are as follows:
Model Opto inputs Relay outputs
P543xxx?xxxxxxK 16 14
P543xxx#xxxxxxK 16 7 standard and 4 high break
P544xxx?xxxxxxK 16 14
P544xxx#xxxxxxK 16 7 standard and 4 high break
P545xxx?xxxxxxK 24 32
P545xxx#xxxxxxK 24 16 standard and 8 high break
P545xxx$xxxxxxK 32 32
P546xxx?xxxxxxK 24 32
P546xxx#xxxxxxK 24 16 standard and 8 high break
P546xxx£xxxxxxK 24 8 standard and 12 high break
Note: ? is for models with only standard output contacts = A, B, C, D, E, F,
G, H, J, K, L, M or R.
# is for models with standard and high break contacts = S, T, U, V, W,
X, Z, 0, 1, 2, 3, 4 or 5.
$ is for models with 32 opto inputs with standard and high break
contacts = 8 or 9
£ is for models with standard and high break contacts = I, N, O, P, Q,
8, 9.
1.9 Logic input mappings
The default m
appings for each of the opto-isolated inputs are as shown in the following table:
Opto-input

P543 relay text Function
1 Input L1 L1 Inhibit Diff
2 Input L2 L2 Interlock
3 Input L3 L3 Aid 1 Receive
4 Input L4 L4 Aid 1 COS/LGS
5 Input L5 L5 Reset LEDs
6 Input L6 L6 Ext Trip A
7 Input L7 L7 Ext Trip B
