Page 20: Zero-Crossing Logic
If inverse time delay is present in the relay, the time delay is determined as though the frequency were at the maximum frequency limit. The definite time delay, if present, is not affected by the frequency limit being exceeded. BE1-81O/U - Functional Description... -
Page 21: Maximum Period Difference Logic
Since the number of pulses is proportional to the sensed frequency difference, the count ends sooner for greater frequency differences and vice versa, creating the inverse time characteristic. If the sensed frequency drops below the 30 hertz BE1-81O/U - Functional Description... -
Page 22: Relay Output
Power Supply Basler Electric enhanced the power supply design for unit case relays. This new design created three, wide range power supplies that replace the five previous power supplies. Style number identifiers for these power supplies have not been changed so that customers may order the same style numbers that they ordered previously. -
Page 23: Section 4 • Installation
If there is evidence of damage, immediately file a claim with the carrier and notify the Regional Sales Office, or contact the Sales Representative at Basler Electric, Highland, Illinois. In the event the relay is not to be installed immediately, store the relay in its original shipping carton in a moisture and dust free environment. -
