Wiring at the Jobsite
1. All cable and conduit should be installed from the tank to control panel
location by the system installer.
USE ONLY NON-METALLIC CONDUIT WITH THE MODEL 197
CONTROL PANEL. METALLIC CONDUIT IS NOT APPROVED
FOR INSTALLATION WITH THE MODEL 197 CONTROL
PANEL.
2. Use only UL listed Direct Burial and non-metallic conduit and wiring for
control and aerator installation.
3. Cable should be carefully measured; cables and wiring must not be
spliced. Spliced connections could result in aerator or alarm sensing
malfunctions.
4. When ordering and measuring cable be sure to:
a. Leave ample cable in aerator mounting casting to install aerator at
desired depth
b. If direct burial cable is used it must be encased in conduit from the
aerator mounting casting to the edge of the concrete tank. It should
not cross over any access covers or panels
c. If direct burial cable is used leave slack in the line to allow for
possible settling in the trench or tank
d. Above grade entrance to the house is recommended if the control
panel is mounted inside the dwelling. If direct burial cable is used
conduit should be in place from the beginning of the foundation to
the entrance of the dwelling.
5. Jet recommends burying cable and conduit at least two feet deep to
prevent accidental damage to the external wiring
6. Proper procedures and solvents must be used to protect the integrity of
the external wiring.
Control Panel Installation
The control panel should be given to the electrician on site for installation. The
installer or distributor must make sure that the control panel settings are correct
for the type of system and components being installed. Refer to control panel
settings section for more information on desired system configurations.
1. Mount the control panel in a location that will be easily accessible, clearly
visible from at least 50 feet and out of reach from children. The panel is
weather proof and can be mounted outdoors. If outdoor installation is
required consideration should be taken to minimize the impact of climate
on the panel. If possible do not mount the panel in direct sunlight.
a. To mount panel remove the panel cover by removing the four
Philips head screws, the panel can then be mounted with the four

screw points adjacent to the corner screw receivers for the panel
cover.
b. Additional mounting brackets are supplied if larger mounting
hardware is desired.
2. After mounting the control panels determine the location of conduit and
wiring for the control panel. Make sure to check local codes and
regulations regarding power requirements.
3. The Jet model 197 control panel is not equipped with knockouts for
electrical conduit connections. Pilot holes must be drilled in the enclosure
to allow conduit access into the panel. For best results use a GreenLee®
punch for the conduit access holes. Make sure the holes are the proper
size for the type of conduit selected. Ideally conduit should enter from the
bottom of the enclosure to increase protection from water infiltration into
the panel. Be sure to avoid damaging the internal components of the
control panel when drilling conduit access holes.
Refer to the Conduit Location Template for conduit entry locations.
4. Attach all conduit and cable connectors to the control panel. Be sure to
follow the manufacturer’s instructions for proper connection installation.
ONLY UL APPROVED WATERTIGHT HUB AND FITTINGS CAN BE USED
WHEN ATTACHING CONDUIT AND WIRING TO THE CONTROL PANEL.
Jet recommends using Carlon or T&B liquidtight non-metallic conduit
and fittings for field installations. Sample instructions have been
provided, refer to the proper model connector fitting instructions
provided by the manufacturer for exact installation instuctions.
5. Assure that all connections are properly installed and watertight.
6. Pull all cables and wiring through the conduit and connectors into the
control panel. Make sure to allow sufficient wiring to make all connection
within the control panel.
7. Make all the appropriate connections to the control panel terminal blocks
as required for the system. If several connections are required it may be
useful to label the inbound and outbound wiring according to the system
design to aid in future maintenance and troubleshooting.
8. The control panel is designed to operate on up to four separate circuits,
depending on the system configuration and local regulatory requirements.
Each individual circuit should be a separate 115-volt, single phase, 60
Hertz AC circuit. Alarm, aerator, and compressor circuits should not
exceed 15 amp breakers from the central breaker panel. The pump circuit
may operate on either 115V or 220V circuit with a 15 amp breaker.
9. Power supply wiring should be at least #14 AWG solid copper wires.
10.A grounding conductor should be installed from the ground buss bar to the
main breaker panel in the dwelling. All system component grounds should
then be connected to the grounding buss.
Failure to connect system components or the model 197 to
proper ground will void any product warranties.

QA-SAL-132 REV 7/31/2013
11.Individual power sources should be connected to the control panel
according to the wiring diagram provided on page 9 of this manual.
12.Additional alarm return and external relay contacts are provided to monitor
and control additional components of the system:
a. Auxiliary Alarm Inputs – there are three additional alarm inputs that
can be operated in either a normally closed (N/C) or normally open
(N/O) alarm state. The alarm state can be reversed by moving the
jumper directly above each alarm input to the desired setting. The
N/O alarm operates on 12 volts AC low amperage circuit.
b. Auxiliary Relay Outputs – there are two additional 120 volt relay
outputs designed to control external relays for operation of external
components. These outputs are 120 volt low amperage and are
not designed to carry any significant electrical load, or to directly
control external pumps or other devices
c. Smaller gauge wire (#16 or #18 AWG) may be used for additional
alarm and relay inputs depending on the proximity of the system
components and the panel.
13.If an integrated pump control is desired the model 197 control panel is
equipped with an internal pump control relay. The pump should always be
operated on an independent circuit. The pump control relay is designed to
supply continuous power to the pump circuit provided there is not an
active alarm condition. In the event of an alarm state the pump control
relay will deactivate power to the pump circuit.
14.Make sure all power supply connections have been fastened securely;
recommended torque for terminal connections is 4 to 5 ft/lbs.
15.Perform an initial power supply test on all available circuits. Ensure that
power from the dwelling is sufficient to properly operate all system
components. All circuits should have 120 volts or equivalent available.
All wiring must be in accordance with local and national
electric codes. Contact your local electrical inspector for more
information regarding proper wiring procedures.
16.Typically the aerator and system components will not be installed at the
time of initial wiring for the system control. The current sensing ability of
the panel will create an alarm condition if there are no components active
during standard operation. The control panel should be left in the off
position until the entire system has been installed.

Aerator / compressor monitoring and control
The aerator 1 circuit is always active and is intended to operate an aerator motor.
The aerator 2 circuit is enabled by DIP switch settings and can be configured to
operate an aerator motor or a compressor. DIP switch settings also configure
the hourly on-time duty cycle of the aerator circuits, which can range for 30
minutes on / 30 minutes off, to continuous run (note – NSF listed J-1500 series
systems must operate on continuous run). The current of each aerator circuit is
controlled by an independent relay. A current transformer in each aerator circuit
is used to monitor the aerator / compressor current. While in normal operation
mode, in the event of an over current or under current condition of any of the
critical treatment components (aerator / compressor) the system will shut down
the affected circuit and enter an automated reset program. The automated reset
program will attempt to re-start the affected circuit after a five minute delay cycle.
If the circuit then functions properly the system returns to normal status, if the
circuit does not function properly then the program enters another five minute
delay cycle. If after the second five minute delay cycle the circuit is will not
function properly the program enters a one hour delay cycle. If the circuit cannot
function properly after the one hour delay cycle the power control relay for the
corresponding aerator circuit is turned off, and the panel enters the alarm
condition, which is indicated by a flashing LED and central alarm beacon, and an
audible signal. If so equipped, the panel will also signal an auto-dialer or modem
to transmit the alarm condition. The over-current or under-current conditions can
be distinguished by different flash rates of the LED and beep rate of the buzzer.
While in test mode the automated reset program will be deactivated. The control
panel may be left in test mode if instantaneous alarm function is required.
Pump motor control
The pump motor control circuit is always active, and the pump motor control relay
will be on.In the event of an alarm condition the pump circuit will turn off power
to the pump.
Auxiliary output control
The active auxiliary output circuits are selectable with the DIP switches. Relays in
the auxiliary output circuits control switching of 120VAC to the output terminal
blocks. The 120VAC is fused on the circuit board and switched by the circuit
board power switch. As currently configured, auxiliary output 1 is intended for
control of the alarm signal beacon mounted to the top of the enclosure, and
causes the beacon to flash in an alarm condition. If Auxiliary outputs 2 & 3 are
enabled, the outputs are on during normal operation and off in an alarm
condition.

QA-SAL-132 REV 7/31/2013
Auxiliary inputs
The auxiliary inputs are intended for sensing the open or closed condition of
additional system components and sensing switches. Typically the auxiliary
inputs are expected to be connected to float switches for sensing water levels.
The active auxiliary input circuits are selectable with the DIP switches. Each
auxiliary input circuit has a jumper selection for normally closed or normally open
operation. The sensing signal at the auxiliary input terminal block is a current
limited 12VAC. Note: Auxiliary contact three will is interlocked with the pump
relay and will deactivate the pump circuit. Do not use this contact for high water
floats in pump tanks.
Indicator LEDs
There is a blue power indicator LED that is lit when power is applied and the
microcontroller is running. There is a one red LED for indication of aerator over or
under current conditions. There are three red LEDs for indication of input error
conditions on the auxiliary inputs. In normal operation, with no error conditions
present, only the blue power indicator LED will be on. Auxiliary alarm circuits
should be properly labeled on the wiring diagram or control panel cover.
Alarm buzzer
The alarm buzzer sounds when an error condition exists. There is circuit board
provision for an externally mounted or alternate model buzzer. When power is
initially turned on, the buzzer will sound for ½ second to confirm that the buzzer
is operational. For purposes of testing or servicing, the buzzer can be silenced
for alarm conditions by DIP switch setting.
Reset switch and master reset switch
The user accessible reset switch has dual functionality. If no alarm condition
exists, and the reset switch is held down for at least two seconds, the
microcontroller will perform a self-reset. If an alarm condition has been triggered,
the reset switch will clear the alarm state. However, if the error condition is still
present, the alarm may immediately re-trigger. After the third reset press with a
continuing alarm condition, the buzzer will be silenced, but the LED error
conditions will not be cleared and no further operation is possible until the panel
is reset by the master reset switch or by removal and reapplication of main
power. The circuit board mounted master reset switch causes a microcontroller
reset.

Auto-dialer interface
The circuit board has a
connector configured to
provide power and a
triggering signal to select
models of commercial,
automatic telephone voice
dialers. If an Auto-Dialer is
installed on the model 197
Control Panel use wire ties
to secure RJ-10 cable to
LED array mounting posts to
ensure there is no contact
between the RJ-10 cable
and 197 control panel
printed circuit board or
components (see image at
right)
RS232 interface circuit
An interface circuit for RS232
communications allows for
connection of the panel to a
computer or other data logging
equipment. If this equipment is
connected to the model 197 Control
Panel use wire ties to secure RS232
cable to LED array mounting posts to
ensure there is no contact
between the RS232 cable and 197
control panel printed circuit board
or components(see image at
below).
Fuse and power switch
The power to the on-board circuitry and to the auxiliary outputs is fused and there
is an on-board power switch for use by service or maintenance personnel.

Start Up Check List
These procedures should be preformed by the Jet installer after all of the system
components and aerators have been connected to the system. This test should
only be conducted after the electrician has completed the panel installation and
before occupation of the dwelling. Refer to the control panel settings and
functions section to review that the proper DIP switch configuration is appropriate
for the system installed.
Make sure that the settings and pump controls are appropriate for the
system configuration and comply with local regulations.
Check the system wiring to ensure the installation instructions have been
followed correctly.
Check to make sure all aerator, pump, and auxiliary connections are
watertight. Ensure there is no exposed wiring prior to turning on the
system.
Set the control panel power switch to the “Off Position”, and then turn
power on at the main breaker panel for all of the system circuits.
Turn on the control panel power, the self test should alarm for two
seconds then all alarms should return to normal state. The blue indicator
light should now indicate that there is power to the panel and circuits.
Check to make sure all system components are operational. If a pump is
connected to the system it may not immediately function depending on
additional float and timer control settings.
Test all inbound and outbound power with a multi-meter. All circuits
should have between 105 and 132 volts AC power supplied to the aerator,
compressor, and pump circuits.
If aerator circuits are set for timer intervals the cycle will begin with the on
aerator condition. To observe aerator timer intervals additional time will
need to be spent on site, or use the “Test Mode” to accelerate the timer
cycles.
If tests are not satisfactory recheck and correct the system wiring as
needed.
Once all checks are completed return the “Test Mode” to its normal
position and reset the control panel with the “Master Reset” switch.
Make sure to correct distributor information is on the front of the panel and
complete the control panel warranty card with the appropriate information.
