Page 3: Warnings, Legal Information And Notes To Ce-Marking And Ul Listing
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. - Page 4 (overfrequency synchronising). Note: This function is not active with t set to ∞. Page 4 of 21 Tel.: (+45) 9614 9614 • Fax: (+45) 9614 9615 • E-mail: deif@deif.com...
- Page 5 LED (SYNC) will be lit, when the busbar voltage is below the dead busbar preset level and the GEN voltage exceeds 80% of nominal value. Please notice that when the voltage on the net has been restored, the CSQ-3 will remain in the dead bus function for a period of 5 seconds.

Mode ∆ The CSQ-3 can be operated in two different modes: ‘Normal mode’ and ‘setting mode’. Normal mode is used to display measuring values, and setting mode is used to view the settings or change them to the desired functionality. -

The operation occurs by means of 3 push-buttons: Mode (toggle), up arrow (▲) and down arrow (▼). Control of settings The mode button is held down for about 2-3 seconds to obtain the setting mode.

At t 0.2 sec. the phase will change 21.6°. As the ∆ϕ window is set to ±10°, the CSQ-3 will calculate that there is no longer space for a t pulse of 0.2 sec.
- Page 20 (∆f) of 0.1Hz = 36°/sec. and t = 0.4 sec. the phase changes 14.4° during the 0.4 sec. If ∆ϕ is set to ±10° the CSQ-3 will calculate that there is space for t . With this setting the synchronising error will be identical with the synchronising error in example 1 (-2.8°) as the breaker closing time is the same (0.2 sec.).
- Page 21 ∆f of 0.05Hz. Function in particular situations: In connection with test “on desk” the CSQ-3 is normally connected to the same supply point so that frequency and phase are completely identical on the generator input and the busbar input. At this test form the following must be noticed: The first time the CSQ-3 is connected, synchronising pulse is emitted whether the ∆ϕ...
