SM345 SOLENOID FLOW CONTROLLER
GENERAL DESCRIPTION
This control module is intended for use with water management systems. Its basic role is to monitor a level probe in a holding tank for a sign that the water has fallen to a specific threshold. When this happens, a Solenoid is activated to allow water to flow into the holding tank.
When the storage tank has reached a higher level defined by a second level probe, the controller responds by deactivating the solenoid.
A third level sensor may be fitted at a higher level to detect a tank overflow condition, whereupon it would trip a separate Overflow alarm.
The control unit has several presettable options that may be engaged by the installer to suit various field situations. A Liquid Crystal Display (LCD) can provide additional information about the status and operation of the unit.
- The controller has a switched 24VAC output via a fuse for activating 24V inlet valves. This is protected by a 1.5A, M205 style fuse.
- The controller has a 230VAC output that operates at the same time as the 24V output, for driving higher voltage solenoid valves.
- A second 240V output will become active during Overflow Alarm conditions.
- Each of the three output relays have an associated red ‘status’ led to indicate relay activity. A single red LED labelled ‘Power’ indicates that mains is connected to the unit.
- A terminal block provides for up to three level probes relative to a common terminal. Probes may be simple conductive metal pins placed within the tank enclosure, or commercial (normally open) float-type level switches. (probe signals are intrinsically safe with less than 5V at under 1ma of current flow)
- An internal Hourmeter & Fill Cycle counter give service staff feedback on tank operation.
- The Front Panel features two push-button switches. The JOG button will force a 30 second solenoid fill cycle. The ALARM MUTE button trips a 6-hour Alarm Mute timer which will mute the audible alarm beeper for 6 hours during overflow Alarm events.
- A blue 10-position rotary selector switch is present to select one of several views on the display for diagnostic functions.
- The unit is housed in a gasketed IP66 enclosure 155 x 115 x 80mm. Where the unit is to be located outdoors, it should be housed in a secondary enclosure to reduce the effects of sunlight, weathering and to limit system access by non-technical staff. (The alarm Mute feature may be extended to a weatherproof button on the outer enclosure.)
- All connections (display socket excepted) are via green unplugable screw terminal blocks.
- An LED indicator and Alarm Beeper are present to signal overflow alarm conditions.
