PANEL MODEL INFORMATION
APPLICATIONS
Superior quality duplex liquid-level controller, auto-
matically controls alternation for two pump operation.
High-level alarm warning designed for a variety of
sump, efuent, sewage and water transfer applica-
tions.
SPECIFICATIONS
• Accepts single or dual power feed.
• 2 hand-off-automatic (H-O-A) pump switches.
• On-off control circuit switch.
• 2 oversized magnetic contactors.
• Numbered terminal strip-screw type.
• Float Switches – Note: Please order oat switches
separately. We offer several types and models. See
the Float Switch bulletin for available options. The
type selected determines the quantity needed.
The basin depth and panel location determine the
required cord length. Contact your distributor or
Customer Service for additional information.
• Electronic pump alternator.
• Alternator selector switch.
• Lag pump start delay.
FEATURES
• Rugged, NEMA 4X construction withstands even the
most severe weather conditions and prevents corro-
sion.
• Provides fully automatic operation for two pumps.
Alternates pump starting to distribute operating
time. Provides extra pumping capacity in times of
high inow by energizing both pumps.
• Alternator selector toggle for maintenance on one
or both pumps.
• Hinged door with lockable stainless steel latch for
safe operation indoors or out.
• High-level alarm circuit includes through-door
mounted silence switch for manual silence of alarm
horn.
• Through-door mounted alarm test switch insures
proper operation of the alarm circuit without the
need to open the panel.
• Two through-door mounted pump run lights.
• Top-mounted high intensity ashing red light pro-
vides 360° visibility.
• Pulsating, corrosion proof alarm horn.
• These duplex controls are factory wired for opera-
tion with three oat bulbs. An easy eld modication
for four oat bulb operation using separate “lag-on”
and “alarm bulbs” is provided.
• Alternator selector switch allows a choice of auto-
matic alternation or operation of only pump 1 or
pump 2. Typically used if one pump is down for
maintenance.
• Lag pump-start delay built-in. Delays starting lag
pump for 5 seconds if both pumps attempt to start
simultaneously as after a power outage.
• Panel can be wired for a single power feed for
pumps and control circuit or the control circuit can
be wired to a separate power supply to insure alarm
integrity in case of a tripped main breaker.
• Auxiliary alarm contacts provided for remote alarm
connection.
• Color coded wiring, screw type terminals and plug
in sockets, ensure ease of eld servicing.
• Field wiring diagram, panel schematic and installa-
tion instructions included.
• Requires three oat switches or with optional fourth
lag oat, order separately.
