8.4.3 “Amp ready” and “Power ready” outputs
If the position references have to be kept when a stored fault is released on the amplifier or when the
power supply is shut down or interrupted, it is possible:
• to reset the defaults via pin 13 of X4 without interrupting the logic supply,
• to have a logic supply which is independent of the power supply (auxiliary supply) in order to be able
to cut the power supply without cutting the logic supply.
If the amplifier has an auxiliary supply on the PR8 connector, which is independent of the power supply,
the J K L jumper on the logic board allows the Undervolt default when switching on the auxiliary supply
before switching on the main power supply.
JK jumper closed and KL jumper open. With the auxiliary supply applied before the main power
supply, the "Undervolt." default is displayed and can hide a default of lower priority. The "AMP READY"
and "POWER READY" outputs are both inactive (contact is open) until the power supply in on.
JK jumper open and KL jumper closed. The "Undervolt." default is inhibited when turning on the
auxiliary supply before switching on the main power supply. The "AMP READY" output is then active
and "POWER READY" remains inactive (contact open) until the main power supply is on. In this case,
the amplifier control must have the following relay logic:
