Issue Resolution
Background
Error 45 can occur on the onboard syringe of the 215 liquid handler or the right hand syringe of the 402 syringe pump but the trouble shooting process is the same for both units as the hardware is the same. There is however a difference in the commands that are required to drive the syringes and this is important if the Gilson Utilities program is used to send commands to the pump. A syringe overload condition can have a variety of causes and only some of them actually cause the syringe drive to be overloaded.
Resolution
Follow the syringe overload trouble-shooting flowchart to determine the cause and correct.
