Power Quality Logger

Safety Instructions

Table 4. 1744/1743 Power Quality Logger - Controls and Indicators

Item	Name	Description
A	Power supply	Power supply voltage range: 88-660 V ac or
	leads and	100-350 VDC, 50 Hz / 60 Hz, 600 V CAT III.
	3-phase plus	Fixed installed voltage input cables for L1 or A,
	neutral voltage	L2 or B, L3 or C, N.
	test leads	The highest permissible nominal voltage for power
		supply input is 660 V.
		The highest permissible nominal voltage for signal
		input is 830 V in a 3-wire network with Delta
		connection.
		In a 4-wire network with Wye connection, the
		highest permissible nominal voltage is 480 V.
		When using PTs and CTs for measuring voltage
		and current in a medium-voltage network, refer to
		the IEC 60044 international standard for
		guidelines.
B	RS232	The serial RS232 interface is used to communicate
	interface port	with a PC. The Logger is connected to the PC’s
		serial port (or a modem for remote communication)
		using the interface cable. Use a USB adapter if
		necessary.
C	START/STOP	The START/STOP button is used to start or end
		switch-operated logging sessions.
D	Channel LEDs	The logging channel LEDs indicate whether the
		applied voltages and currents are within the
		nominal range set using the PQ Log software.
		Continuously on = Logging signal in nominal range
		Short blinks = No or low-level signal
		Long blinks = Overload
E	Power status	Continuously on = Power supply voltage in
	LED	permissible range
		Off = No power
F	Connector for	Flexi sets or current clamps are detected
	Flexi Set or	automatically at power-up. If you change the current
	current clamps	probe type, be sure to remove and restore power so
		the Logger will detect the new current probe.
		Nominal ranges for the Flexi Set are 15 A, 150 A,
		1500 A, and 3000 A ac. Nominal input for current
		clamps is 0.5 V.
G	Logging status	Continuously on = Logging in progress
	LED	Blinking = Logging stopped or not started
