The cooling unit KG-T 500 is controlled by an internal microprocessor. It has been designed to run high speed spindles like in cool ambience conditions. You are able to use it nearly for all types of spindles and cooling blocks. The maximum range of spindle power is 2000W. The KG-T 500 has an integrated and intelligent cooling fluid control. It depends on the temperature of the cooling fluid. According to requirements the fan power will be set to get more or less cooling power. This system runs always in an automatic mode and the users do not need any setting before starting or during...

2. Safety instructions In case of current overload or short circuit you have to be ensured, that the KG-T 500 will be disconnected to power supply. The cooling unit should never operate in an unsupervised run. Be careful by filling the tank of the KG-T 500. Wrong bearing fluid should be immediately taken off by a sponge or a try cloths. Before filling the KG-T 500 with cool fluid, please check the power supply. It should be separated from the cooler und control the de-energized mode of the system. Before starting the KG-T 500 please check all screw connection, cables, pipes and gaskets. Use...

7. Initial operation At first, check the KG-T 500 for external damages of transport. Connect the fluid pipes of the spindle with the KG-T 500 : · Fluid from the KG-T 500 to the spindle set on connector 1 (Flow forward) · Fluid from the spindle to KG-T 500 set on connector 2 (Flow return). DANGER: Before filling the tank with cool fluid, please check the power supply. It should be separated from the cooler unit and control the de-energized status of the system. Now open the tank and fill it to its maximum level. Be careful by doing this. Now use the BMR power cable to set the main supply of...

8. Description of operation After power on the KG-T 500 shows the software version on the display. After a few seconds the operating hours appear on the LCD. When you can read „KG 500 IS READY“ the initiation has been finished. The KG-T 500 is ready to start. The status relay will be energized until the system is ready or in a cooling process. In an error case the status relay will be de-energized. You need an external start signal on connector X1/5 to start cooling process. If there is no start signal the KG-T500 will be set into a standby mode. The fan power depends on the temperature...

When an error appears, it's shown on a blinky display and you can hear an alarm signal. Until an error exists the status relay will de-energized. The relay is connected to X1 pin1-3. You have to analyse the reason for the error and you have to eliminate it quickly. When error has been removed the message on the display will be cleared automatically. If there is no more error the status relay will be energized again. The cooling capacity of the KGT 500 stands during an error message not fully available! The cause of the error should be rectified immediately. Error message on...

11. Installation To assembly the KG-T 500 into a spindle system you need a horizontal under-floor. We allow an addiction to the horizontal of maximum 10°. More addiction may be causes failure of fluid run. Leakage fluid can damage the KG-T 500. The aspirating holes of the cooling unit are on the floor panel. When they are closed the cooling power of the KG-T 500 will be decrease and the efficiency factor decreases, too. Keep them always clean and open. The air delivery ports are on the rear side. Please keep a distance of minimum 10 cm to a wall. The coolant hoses should be kept as short as...
