User Guide OWL
Thank you for selecting a RAMVAC OWL to serve your dental facility.
The RAMVAC OWL provides industry leading technology for convienient and efficient control of your utility room equip-
ment. While we’ve designed the OWL with the ability to control most brands of utility room equipment, its full capa-
bilities are realized when matched with intelligent controllers like those found on RAMVAC manufactured utility room
equipment.
Everything you need to install, operate and program your OWL is found in this manual, so here is all you need to do to
get started:
1. Take a few minutes to read the OWL Overview and OWL Features sections of this manual, to learn mor
about the capabilities of the OWL.
2. The Installation section should answer most of your questions on how to locate and install your OWL in
your facility. But if you do hit a snag, take comfort in knowing our industry leading Technical Service
professionals are just a phone call away and are always glad to help.
3. Once installed, the Operation and Programming sections will make using your OWL a breeze.
We at RAMVAC appreciate your business and take a personal interest in your complete satisfaction. Please let us
know how the system is working for you, by giving us a call or dropping by one of our exhibits at any major dental show.
Please accept my personal invitation to visit our manufacturing facility if you are ever in the beautiful Black Hills of South
Dakota.

OWL Overview
The OWL is a multi-functional, integrated electronic system designed to monitor and control dental utility room equip-
ment from a remote location. When used in conjunction with RAMVAC electronic controls, the OWL provides monitor-
ing, control, and displays alarms. The OWL is also flexible enough to provide start/stop functions for all other brands
of utility room equipment. The compact, attractive, easy to mount control panel features an easy to read LCD screen,
equipment control buttons, program navigation buttons, and LED indicator lights.
(OWLs are individually programmed at the RAMVAC manufacturing facility to meet the specific requirements of each facility)
OWL Features
For RAMVAC equipment:
· Automatic, sequential starting and stopping of up to 8 air compressors and 8 vacuum units based on user demand.
This feature continually sequences equipment on and off to meet varying system needs. The OWL also simplifies
maintenance by apportioning run time on each machine to balance equipment run hours. The OWL can also
simultaneously start and stop up to 8 water control valves.
· Programmable shut-off timer stops equipment at user-defined interval.
· Provides alerts when scheduled maintenance is due.
· Provides alerts when equipment has experienced a fault condition.
· Provides historical operating and fault data.
· Monitors run status of individual equipment.
For non-RAMVAC equipment:
· An Interface Control enables remote start/stop functions for up to 8 air compressors, 8 vacuum pumps, and 8 water
control valves.
· Programmable shut-off timer stops equipment at user-defined interval.

Electrical Connections
Communication Wires
The OWL communicates to the utility room equipment using a RS485 communication protocol across linked communication wires. RAMVAC
recommends using 4 conductor 18 gauge shielded wire , to provide communication and power to the OWL. The A terminal on the OWL must
attach to the A terminal on each of the equipment controls in the system. Likewise, the B terminal will connect to the B terminals on the equipment
controls. The C terminal on the OWL will connect to the shield on the wire. The shield will then connect to the C terminal on the S1 Electrols and
C1 Control, but does not connect to any Interface Controls in the system. Connections A2 and B2 on the OWL are not used.
Power for the OWL
The OWL requires a 12v DC power source to operate. On most systems (see Schematic 1) the power source can be either the S1 Electrols
or the air compressor C1 Control. If using the S1 or C1 for power, connect the 5 terminal on the S1/C1 to the 5 terminal on the OWL and the 6
terminal on the S1/C1 to the 6 terminal on the OWL. (1) These wires can be included in the wire bundle with the communication wires, but
will be connected to only ONE of the RAMVAC equipment controls in the system.
In systems that do not have RAMVAC controls (see Schematic 2), a wall transformer is supplied to provide power to the OWL. Connect the black
with white stripe wire from the transformer to the 5 terminal on the OWL and the black wire with text from the transformer to the 6 terminal on the
OWL.
Interface Control Wiring
The communication wires attach to the A and B terminals per the “Communication Wires” section above, but remember the shield does not
connect to any terminal on the remote module.
(2) A wall transformer is supplied with each Interface Control as a power source. Connect the black with white stripe wire from the
tranformer to the 5 terminal on the Interface Control and the black wire with text from the transformer to the 6 terminal on the Interface Control.
The Interface Control R and Y connections act as a switch to turn on and off any equipment and can handle up to 24 V. See (Schematic 4) for
a typical attachment to a solenoid. In most applications the interface control can be connected in place of the low voltage remote switch typically
used to turn on and off the equipment.
Note: An Interface Control must be used to operate any piece of equipment without a RAMVAC control.
Note: Systems with the optional AutoWash feature require a special Interface Control to control the AutoWash
function. Function of the AutoWash feature is then controlled through the OWL controller instead of the
S1 Electrols.

The following pages contain information on multiple unit systems that will used
when installing and servicing the system.
Use these pages in conjunction with other applicable guides.
The OWL multiple unit system is an automated control system for the control of dental utility room equipment
from a centralized location, convenient to the dental office staff. The system automatically responds to demand so
that clinicians always have the power they need for safe, effortless operation while minimizing energy consumption
and hardware use.
Multiple units automatically selected to run by the computer minimize electrical consumption by operating
according to demand. Multiple pumps offer the advantage of extending service life by reducing the operating hours of
any one pump. Multiplexing inherently adds to backup capacity by decreasing dependency on any one device.
The Owl Controller requires a 12V DC power source to operate. On most systems, power can be provided by
an S1 Electrols or C1 Controller already in the system. On systems without an S1 or C1, a wall transformer provides
power for the OWL Controller.
In the system, the OWL is connected to one of the S1 Electrols mounted to one of the vacuum units or to one
of the C1 Controls mounted to one of the CustomAirby RAMVAC compressors. The system is turned on and off from the
OWL panel and automatically selects the pump with the lowest run-time.
With a 15 to 120 second period of “constant low pressure”, an adjustable pressure switch signals the
microprocessor to turn on units as needed to maintain desired vacuum strength. After the system returns to a
constant “normal vacuum strength” for a period of 15 minutes, unneeded power units are shut down. This “alternation
with record keeping” makes sure your pumps get used evenly with no individual pump working longer than the others.
When using the OWL with generic (other than RAMVAC) units, including vacuum pumps, air compressors,
or water valves, a RAMVAC Interface Control has to be used. It has the ability to communicate with the OWL to start
and stop the generic units but does not have the ability to collect any data. Therefore, for these units the OWL be-
comes a start/stop switch.
