GEC ALSTHOM MCGG52H1CB0753C Communication card

In normal configuration. Interlock is jumpered as shown in Figure 3.22. An opto coupler switch, relay contact or other closure device can replace Link 15 to 16. The interlock when opened disables the power supply output and indicates a control failure on front panel. Pin 14 can be used with an ac source of a range of 24V to 115VAC 50-400Hz or an 18-24VDC source. Connection hookups are shown in the following figures.

INTRODUCTION TO THE RSTL CONTROLLER BOARD 

This board is factory-installed for remote computer control of ESS power systems manufactured by Lambda-EMI. The RSTL is designed to functionally duplicate the voltage and current controls on the front panel of a power supply. These controls select the programming levels and provide metering of the supply output. The RSTL, when set for REMOTE mode, disables the front panel control pot but (the meters still read), and asserts control of the power supply. The RSTL also disables the analog program when in control.
