Emergency Power (AMF) (GCP-32; GCP-31: XPD, XPQ)

NOTE
The parameters for this control are grouped together in blocks to permit navigation through the large
number of configuration screens more rapidly. Selecting "YES" or "NO" has no effect whether or not
control or monitoring is carried out for the parameters located in that block. Selecting "YES" or "NO"
only determines if the individual parameters may be accessed and changed or are bypassed.
Parameter 136
Configure
emergency YES
Configuration of the emergency power (AMF) YES/NO
The emergency power control functions are configured in this block of parameters.
This parameter has the following effects:
YES .............. The parameters in this block are displayed and can either be viewed
("Select" button), or modifications can be made to the parameters
("Cursor→", "Digit↑" or "Select" buttons).
NO ................ The parameters in this block are not displayed, cannot be modified,
and are skipped.
NOTE
Emergency power functionality is only possible with synchronous generators utilizing a minimum of a
mains circuit breaker and a generator circuit breaker (i.e. GCP-32 or GCP-31 with LS 4 coupling).
Prerequisite: The emergency power function (AMF) may only be enabled with synchronous generators by con-
figuring "Emergency power" (Parameter 136) as "ON". Emergency power operat
ions are only performed in the
AUTOMATIC or TEST operation modes regardless of the status of the "Automatic 1" and "Automatic 2" dis-
crete inputs.
NOTE
If the "Engine enable" or "Engine block" function is assigned to terminal 6 (Parameter 212), emergency
power operations can be prevented or interrupted from an external source through a discrete input. Re-
fer to "Terminal 6" on page 116.
If Parameter 209 is configured ON and discrete input 11 (terminal 68) is energized, emergency
power
operation will also be prevented or interrupted (refer to Enable 'Emergency OFF' via terminal 68 on
pa
ge 114).
Activation of emergency power: If a mains voltage fault (over-/undervoltage, -frequency or phase/vector jump)
is detected on any single phase of terminals 50/51/52 continuously for the duration of the emergency power start
delay time (Parameter 138), an emergency power operation is activat
ed. A mains voltage fault is defined as fol-
lows: If the mains voltage and frequency monitoring (Parameter 179 and/or Parameter 184) are enabled and the
configured lim
it has been exceeded. If either or both the mains voltage and frequency monitoring are not
enabled, the internal default limits will be used for protective limits. The internal protective limits are defined as
follows:

An emergency power operation (AMF) may also be initiated through the detection of a breaker fault when the
MCB is closed. This protection will only occur if "Emergency power" (Parameter 137) and "MCB monitoring"
(Parameter 131) are configured as "ON".
