Application
The control relay, CR, is incorporated into the control scheme to prevent the transfer of the load to the standby power source until the source has reached an acceptable level of voltage and frequency. In doing so, there will be little chance of damage due to low voltages or low frequencies. If the standby power source can only produce voltage an insufficient frequency or frequency and insufficient voltage the Robonic Automatic Transfer Switch will not transfer to the standby power.
When the standby power source is supplying sufficient voltage and frequency, this relay will operate its contacts and initiate transfer. Upon restoration of the normal supply, device EN will open its contact in the control relay circuit causing the relay to
