User manual, Check synchroscope CSQ-3
4189340263L (UK)
1. Warnings, legal information and notes to CE-marking and UL
listing
This manual gives general guidelines on how to install and operate the CSQ-3.
Installing and operating the CSQ-3 implies work with dangerous currents and voltages.
Therefore this should only be done by qualified personnel. DEIF A/S takes no
responsibility for operation or installation. If there is any doubt about how to install or
operate the system on which the CSQ-3 is measuring, the company responsible for
the installation or the operation must be contacted.
The CSQ-3 is CE-marked with respect to the EMC directive for residential, commercial
and light industry plus industrial environment. This covers all environment types where
the CSQ-3 can normally be used.
The CSQ-3 is CE-marked with respect to the low-voltage directive for up to 600V
phase to ground voltage, installation category (overvoltage category) III and pollution
degree 2.
The CSQ-3 can be delivered with UL listing. Please refer to the section “Technical
data” for installation information as required by the UL.
The package contains the following items:
•
Check synchroscope CSQ-3 unit
•
User manual
•
Two fixing clamps
•
A plugable connection (mounted on the unit)
•
Cable for system status output (only marine version)
2. Application and functionality summary
The CSQ-3 check synchroscope is a microprocessor-based synchronising unit
providing measurement of all relevant values for synchronising a generator to a net
(busbar). It is used in any kind of installation where manual or semi-automatic
synchronising is required.
In the CSQ-3 there is a possibility of adjusting the following synchronising
requirements: The voltage difference between GEN and BB, the size of the phase
window and the length of the synchronising pulse.
In addition to that there is an indication of ‘U
GEN
TOO HIGH’ or ‘U
GEN
TOO LOW’ (red
LEDs), phase difference within the preset window ‘
ϕ
OK’ (yellow LED), and finally
synchronising output active, ‘SYNC.’ (green LED).
