SM302 DUAL SPRAY VALVE / SPRAY PUMP CONTROLLER
GENERAL DESCRIPTION
In situations where one or two spray valves or pumps, deliver water to a tank that can only discharge at a slow rate, there is a risk of overflow. The SM302 is designed to treat this problem
By passing the spray valve or pump control through the SM302, a High Level Alarm sensor can report faults by relay contact , audible alarm, and flashing LED lamp. In the event of a High Level Alarm it will isolate the spray valves until levels have fallen.
An adjustable timer (settable between zero and 200 seconds) will provide a 'wait' time after a High Level Alarm. It will inhibit the two output relays until there has been sufficient drain time in the sump tank. This prevents excessive cycling of output sprays.
Unit will switch 24V or 240V AC loads. Built in hour meter also tracks hours of flow operation.
The control unit has several presettable options that may be engaged by the installer to suit a range of field installations. A Liquid Crystal Display (LCD) provides additional information about the status and operation of the unit. An internal Hour Meter may be viewed which tracks the number of hours and minutes that each output has operated since the system was first installed.
- The module is 155 x 115mm. It is housed in an IP66 enclosure, 125 x 165 x 75mm, to keep it free of dust, moisture and to limit access by non-technical staff.
- Each 240VAC output terminal block can support a load to1500 watts, 7.5A. All electrical connections (except for the display socket) are via green unplugable screw terminal blocks.
- A large LED and Piezo beeper are present on the board to signal overflow alarm conditions.
- A relay controlled 24V, 200ma AC outlet is provided via a 2-way terminal block, to drive an external spray solenoid. This is protected by a 1.5A, M205 style fuse.
- Each of the three power relays have an associated red ‘status’ led to indicate relay activity. A single red LED labeled ‘Power’ indicates that mains is connected to the unit.
- A four-way terminal block provides the termination point for up to three moisture conductivity or level probes relative to a common conductor. 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 less than 1ma of current)
- A 3-way terminal block provides the termination point for two momentary-action push button switches. The JOG switch will force a 20 second operate cycle for both switched outputs. The Alarm Mute switch trips a 6-hour Alarm Mute timer which will block the sound of the audible alarm beeper for 6 hours during high-level alarm.
- Two option links labeled LK1 and LK2 may be placed into either an A or B position to select installation options. LK1 may be used to ‘Fast Forward’ several of the internal time delays to allow installers to test a system without having to wait for long time periods. ( LK2 is not in use with this model controller)
- A small, blue 10-position rotary selector switch is present to select one of several views on the display for the operator to monitor the system status and to adjust wash down spray delay times from 1 to 6 hours.
