## 0x0A
ELU-A Load Exceeded

Default definition: |  | ERROR |
Default limit: |  | 100 |
Used by block: |  | RP (ELU-A) |
Category: |  | MAINTENANCE |

The allowed continuous power dissipation on the ELU-A board is exceeded, which may effect the component durability. This situation can be accepted for a short time during high traffic without measurable negative effects. If this warning occurs often or during low traffic, measures should be taken to spread out the traffic over several ELU-A boards. If only one ELU-A board is available, a 200 ohm resistor should be inserted in series with each branch of the extension line in order to decrease the power dissipation. Three power limiting actions for the SLIC circuits are used by the ELU-A software:

Limit 1: voltage feed is decreased.

Limit 2: current feed changed to 850 ohm.

Limit 3: idle SLIC circuits are disabled.

- D1: Current power limit

- Bit 7 = 0: Power limit 2
- Bit 7 = 1: Power limit 3
- Bit 6 - 0: Number of lines

- D2: Counter value for power limit 1.
- D3: Counter value for power limit 2.
- D4: Counter value for power limit 3.
