Keep Control: PULPO 2ESO‘s new housekeeping unit
Christoph Geimer, Claudio Cumani, Nicolas Haddad, Javier Reyes, Javier Valenzuela, Bernhard Lopez
PULPO 1 BACK PANELPULPO 1 FRONT PANEL
• 6 temperature sensors PT100• 3 independent heater circuits• Shutter control• Vacuum monitoring• 1 alarm output• simple RS 232 interface• 33 units already build, very low failure rate• Standard housekeeping unit at all optical ESO instruments
THE BEST THING WE HAD TO OFFER - PULPO 1
NEW CHALLENGES - OmegaCAM
• PULPO 1 functionality plus:• much more sensors (at least • more alarm outputs • data logging• increased safety features

Interfacing to the world
• 29 PT100 temperature sensors by default, up to 125 via external multiplexers
• digital I/O control and power supply for external MUX board
• Vacuum monitoring (Balzers or Edwards gauges)
•seperated alarm outputs for vacuum and temperature (2 for each)
• fiber interface to SLCU
• additional standard RS 232 interface
• Ethernet connection for log data download and
• OPTO isolated shutter interface ( 1output, 4 inputs,2spares)
• 8 independent heater circuits (72W, +-0.1K accuracy)
• data logging capabilities with 65000 records
• self recovery
