SJE Rhombus NEMA 4X User manual

This control panel must be installed and serviced by a
licensed electrician in accordance with the National Electric Code
NFPA-70, state and local electrical codes.
All conduit running from the sump or tank to the control panel
must be sealed with conduit sealant to prevent moisture or gases from
entering the panel. NEMA 4X enclosures are for indoor or outdoor
use, primarily to provide a degree of protection against corrosion,
windblown dust and rain, splashing water and hose-directed water.
Cable connectors must be liquid-tight in NEMA 4X enclosures.
The Subsurface Drip control panel is designed to control one single-
phase pump (simplex) or two single-phase pumps (duplex), and two
valves. The installer can program a PLC containing all the timer set-
tings and monitoring information for the system. These changes are
made with the touch pad and screen display on the PLC. The panels
are designed to be used with four floats. They are: low level, timer on,
override, and high water alarm.
Low Level - Used as a redundant off to insure the water level
can not be pumped below this float. The audible and visual
alarm will activate.
Timer On -Activates a repeat cycle timer that starts in the Off
mode.
Override Timer - Starts a different repeat cycle timer used to
increase the dose cycle.
High Water Alarm - Activates the audible and visual alarm.
Installation of Floats
CAUTION: If control switch cables are not wired and mounted in the
correct order, the pump system will not function properly.
WARNING: Turnoff allpowerbeforeinstallingfloatsinpumpchamber.
Failure to do so could result in serious or fatal electrical shock.
1. Determine your normal operating level, as illustrated in Figures 1
& 2.
2. Mountfloatswitchesat appropriatelevelsasillustrated inFigures 1
& 2.Be sure that floats have free range of motionwithout touching
each other or other equipment in the basin.
3. For mounting clamp installation: place the cord into the clamp as
showninFigure 3.Locatetheclampatthe desired activation level
and secure the clamp to the discharge pipe as shown in Figure 3.
NOTE: Do not install cord under hose clamp.

Installation Instructions
Mounting the control panel
1. Determine mounting location for panel. If distance
exceeds the length of the float switches or pump,
splicing will be required. You must use conduit
sealant to prevent moisture or gases from enter-
ing the panel.
2. Mount control panel using the mounting flanges
furnished with control panel.
3. Determine conduit entrance locations on control
panel. Check local codes and schematic for the
number of power circuits required.
NOTE: Besure the incomingpower, voltage, amper-
age, and phase meet the requirements of the pump
motor being installed. If in doubt, see the pump
identification plate for electrical requirements.
4. Drill proper size holes for type of connectors being
used.
5. Attach cable connectors and/or conduit connectors
to control panel.
FOR INSTALLATION REQUIRING A SPLICE,
FOLLOW STEPS 6-10;
FOR INSTALLATION WITHOUT A SPLICE,
GO TO STEP 11.
6. Determine location for mounting junction box(es)
according to local code requirements.
7. Mount junction box to proper support according to
local codes.
8. Run conduit to junction box(es). Drill proper size
holes for the type of conduit used.
9. Identify and label each wire before pulling through
conduit into control panel and junction box(es).
Make wire splice connections at junction box(es).
10. Firmly tighten and seal all fittings on junction
box(es).
11. If a junction box is not required, pull cables
through conduit into control panel.
12. Connectpumpwiresandfloatswitchestoproper
position on terminals. See schematic inside control
panel for terminal connections.
NOTE: It is the recommendation of the factory to use
separate pump and control/alarm power sources.
VERIFY CORRECT OPERATION OF CONTROL
PANEL AFTER INSTALLATION IS COMPLETE.
4. Tighten the hose clamp using a screwdriver. Over
tighteningmay resultindamage totheplastic clamp.
Make sure the float cable is not allowed to touch
the excess hose clamp band during operation.
NOTE: All hose clamp components are made of
18-8 stainless steel material. See SJE-Rhombus®
for replacements.

Operations
TheSubsurface Dripcontrolpanel isdesignedtocontrol
one single-phase pump (simplex) or two single-phase
pumps (duplex), and two valves. The installer can
program a PLC to contain all the timer settings and
monitoring information for the system. These changes
are made with the touch pad and screen displays on
the PLC.
Float Switches
Four float switches are used to monitor the water
heightinthetank.The water height will determine what
function the control panel will perform.
PLC/Control
The control panel contains a PLC used for all the
timing sequences required. Motor contactors are used
for pump operation. Circuit breakers are provided for
the pump circuits and fuses for the control and valve
circuits.
High Level Alarm Float
This float activates the alarm audible and visual alarm
when lifted. The audible alarm may be silenced with
theexternaltest/normal/silence switch.Thisswitchwill
also test the audible and visual alarm.
Override Float
Thisfloatactivates the override repeat cycle timer.The
timer will cycle the pump at a faster rate. This timer will
start in the off mode.A complete dose will occur when
the on time is activated even if the float drops.
Timer On Float
This float activates the repeat cycle timer. The timer
will control pump cycles beginning in the off mode.
Low Level Float
This float turns off the pump(s) when lowered. The
float will override all timers to insure the pump will not
run when the water level drops below the float. The
audio/visual alarm will also be activated.
Pump & Valve Operation:
The pump dosing cycles will be controlled by the
timers. During high flow conditions, the pump(s) will
be controlled by the override timer.
When the timers call for a dose, the following
operation will occur:
1. The pump will turn on and the spin filter valve
will be activated for the programmed time.
2. The spin filter valve will then close and the
pump will continue to run for the timer on or
the override timer on time.
3. The pump will continue to run and the flush
valve will be activated for the programmed
time.
4. The pump will then be turned off and the flush
valve will remain on for the programmed drain
time.
5. The flush valve will then close for the pro-
grammed off time.
After the programmed number of pump cycles, the
flush valve will remain activated during a dose on time
for each zone. This will occur until each zone has
been fully flushed.
Manual Operation
Internal to the panel there are valve and pump Hand/
Off/Auto (HOA) switches for manual control of these
devices.
(H) - manually runs the device
(O) - turns the device off.
(A) - sets the device to Auto Mode for PLC control.
Duplex Models Only:
Pump Operation
The pumps in a duplex system will be alternated at
each dose. Only one pump will run at a time.
NOTE: When both pumps are placed in the Off mode,
they must be reset by first placing them in the Hand
mode before placing them in the Auto mode.
