Toro Micro-Master® 4500 Plus Series Controllers
The improved Micro-Master 4500 Plus controller is used in horticultural and agricultural applications with Filter Flushing and Chemical Fertiliser Injection Programs
Station watering options
0-9999 seconds, 1 sec. increments 0-9999 minutes, 1 min. increments 0-9999 volume units, 1 unit increments
Auto Skip Facility: A1: 0-250 secs at irrigation start to allow system to stabilize A2: Operational Scanning time/frequency (0-250 secs)
In group mode, the seven terminals allotted to chemical injection and filter flush can be used for irrigation valves if chemical injection/filter flush not used Operation
Fault Reporting Monitors flow or pressure switches connected to the ASKIP terminal and utilises the auto skip programmable delay times Memory
9 volt Alkaline battery (included) keeps correct time during power failure (150 hours nomimal) Power Sources
Extensive Protection against field and mains power surges
Relay outputs to field valves ensures reliable operation under the most severe conditions
Isolated logic board protected by additional transformer which diverts surges to earth Communications/Software
