Chapter 5 Commissioning P O W E R I N G T E C H N O L O G Y 5.1 Commissioning Overview Before delivery the system was thoroughly inspected and tested. The following chapter is a guide to the set-up and operation of the control functions of the system. NOTE Before starting commissioning read the product description for the individual components.
P O W E R I N G T E C H N O L O G Y 5.4 Commissioning procedure 1. Remove the covers and check that all connections are made according to the installation drawing. Verify that all connections are properly tightened with sufficient torque. 2.
P O W E R I N G T E C H N O L O G Y 5.5 Test of output voltage 5.5.1 Float charge (U1) Ensure that the controller is operating. Connect a load, approx. 50% of total capacity, to the system. Check the voltage according to the battery manufacturer’s requirements.
Temperature compensation is factory pre-set. Check that the temp. probe is activated and verify that the compensation level is in accordance with the battery manufacturer’s requirements. (If no compensation level is available from the battery manufacture, UNIPOWER recommends that it is set to 0.5V).
P O W E R I N G T E C H N O L O G Y 5.8 Commissioning record This is a step-by-step commissioning record for easy commissioning of Power Supply Systems. Do not continue if any faults occur during this commissioning. The checkpoints are to be considered as a minimum for commissioning of the system.
If the first step of the recommendation does not solve the problem continue to the next one. NOTE If the malfunctioning of the system persists, please contact UNIPOWER technical support. NOTE For a description of Alarms and Messages generated by the system controller see...
