Analog Predefined Alarms

General Description

The EcoStruxure Power Commission software enables the configuration of analog predefined alarms.

Analog predefined alarms:

may be modified via the command interface in configuration mode
are only available with a MicroLogic H trip unit
can be used to trigger waveform capture

Analog Predefined Alarm Record

Analog predefined alarms are coded on 12 registers.

The order and the description of the analog predefined alarms are the same as that of analog predefined alarm 1:

Analog Predefined Alarm 1
Address	Register	RW	X	Unit	Type	Range	A/E/P/H	Description
0x176F	6000	RW	–	–	INT16U	–	H	The MSB gives the activity of the alarm: 0 = On 1 = Off The LSB gives the priority of the alarm: 0, 1, 2, or 3. The factory setting value is 0x0101. Register set to 0 will not log event into the event log (file number 10) and Waveform Capture file (file number 5).
0x1770	6001	R	–	–	INT16U	1016	H	Register number which content gets in relation to the pick-up value and to the drop-out value. The factory setting is 1016.
0x1771	6002	R	–	–	INT16U	–	H	Comparison mode: The MSB indicates Pickup mode. The LSB indicates the Dropout mode. MSB and LSB can be set to 1, 2 or 4: 1 = immediate mode (register 6003 contains the numerical value to which the monitored register is compared) (factory setting for pickup mode and dropout mode) ⁽²⁾ 2 = direct mode (register 6003 contains the register number of the register that is in relation to the monitored register) (percentage is applied) 4 = selects bit test mode (register 6003 must contain the bitmask that gets compared (AND operation) to the monitored register)
0x1772	6003	RW	1	–	INT16U	–	H	Alarm actuation pick-up value ⁽¹⁾ The factory setting is 0x8000.
0x1773	6004	R	100	%	INT16U	–	H	This register contains a numerical value that is multiplied by the content of the pickup register when Direct Mode is selected. Otherwise, register is not used. The factory setting is 0x8000.
0x1774	6005	RW	1	s	INT16U	–	H	Actuation time delay The factory setting is 0x8000.
0x1775	6006	RW	–	–	INT16U	–	H	Release pick-up value ⁽¹⁾ The factory setting is 0x8000.
0x1776	6007	R	–	%	INT16U	–	H	This register contains a numerical value that is multiplied by the content of the pickup register when Direct Mode is selected. Otherwise, register is not used. The factory setting is 0x8000.
0x1777	6008	RW	1	s	INT16U	0–3000	H	Release time delay. The factory setting is 0x8000.
0x1778	6009	R	–	–	INT16U	0–3	A/E	Alarm type: 0 = Over 1 = Under (factory setting) 2 = Equal 3 = Different from 5 is used for all other alarms.
0x1779	6010	RW	–	–	INT16U	–	H	Action associated with overrunning of the pick-up value after the time delay has run out. Log into the Waveform Capture file (file no. 5). Bit 9 set to 1 = action activated The factory setting is 0.
0x177A	6011	–	–	–	–	–	–	Reserved
(1) When Immediate mode is selected, care must be taken to set this register with the same units and scale factors as the register 6001. (2) No percentage is applied.
