TABLE 31. CONTROL PANEL FEATURE/BENEFIT DESCRIPTIONS
Option Bene t
IR (intrinsically safe relay) The intrinsically safe relay option is required for systems with tanks in applications classi ed as hazardous locations
(Class I, Division 1) (UL 698A). Intrinsically safe control panels are designed so that the energy delivered to the  oats
is insuf cient to cause an ignition of a  ammable gas in the tanks. One intrinsically safe relay is required for every two
 oats. The panel nomenclature indicates how many relays are included with the panel. For example, DAX1IR2PTRO
would indicate two relays for use with up to four  oats.
PT (programmable timer) The programmable timer allows the system to be timed-dosed. Timed dosing provides superior wastewater treatment
by delivering the ef uent in discrete doses at regular intervals and can reduce the chances of saturated soil conditions
due to hydraulic overloading. A properly set timer is matched to the design  ow of the system and allows for early
detection of system abuses, before major damage occurs. Recommended for all treatment systems.
RO (redundant off  oat) The redundant off option uses a signal  oat to prevent pumps from operating when there is not enough liquid in the
tank. This helps to prevent damage to pumps by activating an alarm during abnormally low level conditions. The
redundant off option also detects leaky tanks or systems that are siphoning. In addition, the redundant off  oat acts as
a backup in case another  oat gets stuck. Recommended for all pumping systems.
CS (current sensor) Current sensors monitor pump operation and are used to detect a pump failure in systems where a pump failure will
not necessarily lead to a high-water alarm condition. With a current sensor, an alarm will be activated if the pump
is called to run, but pump current is not detected. Current sensors are highly recommended in systems in which it
may be dif cult to detect a pump failure, such as a duplex alternating system. Recommended for commercial
systems.
DS (disconnect switch) The disconnect switch option allows for a single shut-off point for all power entering a panel. This switch is an easy
means to disconnect power when maintenance needs to be done or when there is an emergency.
RA (remote alarm) The remote alarm option provides a dry contact closure in the panel for connection of external devices that might use
voltages up to 240 VAC. (All Orenco control panels include a 120 VAC output to activate remote alarms.) The remote
alarm option is especially useful for phone dialers and is recommended when voltage needs are unknown.
TS (test switch) The test switch option provides a single switch that can be used to con rm the operation of the alarm light and audible
alarm.
HT (heater) The heater option keeps the panel warm in cold weather and reduces panel condensation. The heater automati-
cally adjusts its output wattage with varying temperature. Recommended for all MVP, PLC, and telemetry
control panels.
ETM (elapsed time meter) The elapsed time meter option provides an electromechanical totalizing meter that records the total time that a pump
has been called on to run by the controls. The run time can be used to calculate  ow through a system. (An elapsed
time meter function is built into MVP and telemetry panels as a standard.) Recommended for all pumping
systems.
CT (counter) The counter option provides an electromechanical totalizing meter that records the total number of cycles that a pump
has been called on to run by the controls. When combined with the ETM option, variances in the counter activity can
reveal problems with pumps or  oats. (A counter function is built into MVP and telemetry panels as a standard.)
PRL (pump run light) The pump run light option provides a green light on the front of the panel enclosure that will illuminate when the pump
is called to run by the controls.
PL (power light) The power light option provides a green light on the front of the panel enclosure that will illuminate when the control
panel has power.
SA (surge arrestor) The surge arrestor option reduces system performance problems caused by power irregularities, such as surges and
spikes. Recommended for MVP, PLC and telemetry control panels.

Orenco Systems
®
specializes in designing and manufacturing control and
monitoring systems for the water handling and wastewater industries.
Our experts know what issues are important to designers, engineers,
and system operators. From simple alarms, to tried and true standard
(electromechanical) panels, to MVP (digital programmable) panels, to
Web-based remote telemetry control systems, to custom-built real-time
networked remote telemetry control systems, Orenco offers the best
value for your dollar.
We use the  nest, precision-engineered components available, and we
back our panels up with ongoing research, years of applied experience,
and a three-year warranty. Available with UL 508 and 698A listing for
industrial control panels in the US and Canada. CE marking available
for European markets.
These panels have been designed for use in the onsite industry, but
they can also be used in many other applications. Our standard control
panels, customized panels, remote telemetry panels, and Web-based
monitoring system are unsurpassed in the control system industry.
