Specifications

RMIS Part No. 500549 Rev. B Page 3
• Built-in self-test allows you to test various internal circuitries utilizing built-in test
capability.
• Non-volatile memory to retain the pro
g
ram(s) and controller information durin
g
power
outages or seasonal shut downs. This information is maintained indefinitely.
• A "real time" clock with non-volatile backup to maintain the actual date and time
during power outa
g
es without the need of batteries. This eliminates the need to
reprogram the clock every time there is a power outage.
• Advanced circuitry to automatically monitor internal voltages and reset on-board
microprocessor circuitry during power “brown-out” or error conditions.
• Automatic electronic fuse which resets intelli
g
ently based upon need. (No user fuses or
circuit breakers to reset or fail.)
• Intelli
g
ent resumption of pro
g
ram execution after power outa
g
es to ensure that
program starts are not lost. The controller intelli
g
ently schedules irri
g
ation after any
outage while preserving the original water window.
• Automatic detection of main line water breaks. Upon detection the controller shall:
shutdown all active irrigation, energize a Normally Open Master Valve (if selected),
condemn any future start times, and trigger audible and visual alarm indicators.
• Automatic detection of unscheduled water flow. Upon detection the controller shall:
activate the Normally Open Master Valve (if selected), condemn any future start times,
and trigger audible and visual alarm indicators.
• Automatic detection of upper stations flow limit. Upon detection the controller shall:
turn off the fault station, advance the pro
g
ram to the next station, condemn the
station from any future watering times, and trigger audible and visual alarm indicators.
2.0 FLOW CAPABILIITES
The controller shall have:
• Programmable flow to enable or disable the flow sensor features.
• Programmable flow sensor pipe sizes for standard Rain Master flow sensors (1.0, 1.25,
1.5, 2.0, 3.0, and 4.0 inch). Non-standard pipe sizes are also programmable.
• Inputs for connectivity to a flow sensor. The controller shall read the frequency of the
sensor by sensing each time a contact closure appears at the input. The controller shall
source +8 VDC to the sensor.
• Programmable main line flow limit from 1-999 GPM defines the maximum allowable flow
during scheduled irrigation.
• Automatic detection of main line water breaks. Upon detection the controller shall:
shutdown all active irrigation, energize a normally open master valve (if selected),
condemn any future start times, and trigger audible and visual alarm indicators.
• Programmable unscheduled flow limit from 0-999 GPM defines the maximum amount of
flow which will be tolerated during unscheduled irrigation periods.
• Automatic detection of unscheduled water flow. Upon detection the controller shall:
energize the normally open master valve (if selected), condemn any future start times,
and trigger audible and visual alarm indicators.
• Programmable station upper flow limits from 0-500 GPM.
• Automatic detection of upper stations flow limit. Upon detection the controller shall: turn
off the fault station, advance the program to the next station, condemn the station from
any future watering times, and trigger audible and visual alarm indicators.
