1.2 Safety

1.2.1 Safety Alert Symbol

SAFETY INSTRUCTION

This safely alert symbol will be used in this manu­al to draw attention to safety related instructions.
When used, the safety alert symbol means

ATTENTION, BECOME ALERT! YOUR
SAFETY IS INVOLVED! FAILURE TO
FOLLOW THIS INSTRUCTION MAY RESULT
IN A SAFETY HAZARD.

1.2.2 Safety Instruction Decal

Your Technologic

should have a safety instruction dec al (part #
S11550) located on the front of the enclosure near
the disconnect switch. If the decal is missing or illegi­ble contact your local B&G representative for a
replacement.

1.2.3 Hazardous Voltage

Only qualified electricians should perform electrical

service of any kind on the control panel or pumping
system. Visually inspect the control panel for loose or
stranded wires and for damaged components or wires
prior to performing electrical service. Never trouble­shoot or perform service on a live control panel. Do
not turn the disconnect switch on while the enclosure
door is open. Live voltage is still connected to the
incoming side of the disconnect switch even when the

®

Constant Speed Pump Controller

disconnect switch is off. Turn off and lock out the
incoming power prior to troubleshooting or perform­ing service on this control panel.

WARNING: High Voltage! Do not work

on live control panels. Disconnect the
incoming power prior to performing service on
this unit. FAILURE TO FOLLOW THIS

INSTRUCTION MAY RESULT IN DEATH OR
PROPERTY DAMAGE.

1.2.4 Pump/Motor Safety

All electrical installation or service on the motors

should be performed by a qualified electrician.
Ground fault protection should be sized properly.
Refer to local electrical codes for sizing and selection.
Refer to the I.O.M. for the motors for specific instal­lation information. Even when the Pum ps are
stopped, they should be considered alive as long as its
controller is energized. Keep hands away from the
pumps until the power is disconnected from the
pump controller.

1.2.5 Motor Control Equipment Safety

Do not install and operate a pumping package in a

closed system unless the system is constructed with
properly sized safety and control devices. Such devic­es include the use of properly sized and located pres­sure relief valves, compression tanks, pressure con­trols, temperature controls and flow controls as
appropriate. If the system does not include these
devices, consult the responsible engineer or architect
before making pumps operational.

DANGER: The heating of water and

other fluids causes volumetric expansion.
The associated forces may cause failure of system
components and release of high temperature flu­ids. This will be prevented by installing properly
sized and located pressure relief valves and com­pression tanks. FAILURE TO FOLLOW THESE

INSTRUCTIONS CAN RESULT IN SERIOUS
PROPERTY DAMAGE AND SERIOUS
PERSONAL INJURY OR DEATH.

1.3 Storage

For long periods of storage, the pumping package

should be covered to prevent corrosion and contami­nation from dirt. It should be stored in a clean, dry
location between -20 and +60º C. The relative
humidity should not exceed 95%. The unit should be
checked periodically to ensure that no condensation
has formed. After storage, check that it is dry before
applying power.

1.4 Handling

Care should be taken to prevent damage due to drop-

ping or jolting when moving any panel or pumping
package. Transportation damage should be brought
to the carrier’s attention immediately upon receipt.

Technologic® Constant Speed Pump Controller Installation, Operation and Maintenance Manual 6

General

The unit should be unloaded and handled by quali­fied personnel. A pumping package that includes this
panel may be top heavy due to the position of the
motors. Lift the unit with slings placed under the unit
base rails. Be sure not to load the lifting mechanism
beyond its rated limits. Use the motor eyebolts to sta­bilize the unit while lifting to prevent overturning.

DANGER: Heavy load, may drop if

not lifted properly. Do not load cables,

chains or hoists beyond their rated limits.

FAILURE TO FOLLOW THESE INSTRUC­TIONS COULD RESULT IN SERIOUS
PERSONAL INJURY, DEATH AND/OR
PROPERTY DAMAGE.

1.5 Foundation

A concrete base weighing at least 2.5 times the weight

of the pumping package is recommended. Check the
shipping ticket for the unit weight. Tie the concrete
pad in with the finished floor. Use foundation bolts
and larger pipe sleeves to give room for final bolt
location.

1.6 Leveling

Place the pumping package on its concrete founda-

tion, supporting it with steel wedges or shims totaling
1” in thickness. These wedges or shims should be put
on both sides of each anchor-bolt to provide a means
of leveling the base.

1.7 Location

Install the pumping package appropriately for ease of

inspection, maintenance and service. Observe local
electrical codes concerning control panel spacing.

1.8 Piping

Be sure to eliminate any pipe strain on the pumping

package. Support all pipes independently by use of
pipe hangers near the unit. Ordinary wire or band
hangers are not adequate to maintain alignment. It is
very important to provide a strong, rigid support for
the suction and discharge lines. A saddle hanger is
recommended. Do not attempt to force the suction
or discharge lines into position. Refer to the assembly
drawing for customer piping connections.

Inspect all unit piping connections. Joints may also

become loose during transit due to vibration and
shock. All joints should be checked for tightness.
Flanged joints should be checked for proper torque
of all flange bolts prior to filling the system with
fluid.

Eccentric increasers may be used in the suction lines

when increasing the pipe size, with the straight sides
of the increaser on top to eliminate air pockets.

For critical installations, equipment for absorbing

expansion and vibration should be installed in the
inlet and outlet connections of the unit.

Drain plugs are placed in a cloth bag and secured to

the unit prior to shipping from the factory. Reinstall
the drain plugs prior to filling the system with fluid.

On an open system with a suction lift, use a foot

valve of equal or greater area than the pump suction
piping. Prevent clogging by using a strainer at the
suction inlet next to the foot valve. The strainer
should have an area three times that of the suction
pipe. Provisions must be made to prime the pump
suction piping on start up. Do not start the pump
unless all suction piping is full of water.

A thermal relief valve is installed on the discharge

header to prevent potentially dangerous thermal
buildup in the package. This valve acts as a safety
device and it should never be removed or tampered
with. It is factory set to open and discharge when the
water temperature in the discharge header exceeds
125°F. The 3/8” NPT opening of this valve must be
piped to a floor drain.

Before starting, all pumps and motors should be

checked for proper lubrication.

1.9 Temperature and Ventilation

The operating temperature range for this unit is 0 to

50°C. The relative should be kept between 10% and
90% non-condensing. The unit should not be operat­ed outside these extremes.

1.10 Incoming Power and Ground Wiring

A qualified electrician should bring incoming power

and ground wiring to the disconnect switch. If holes
are drilled in the control panel, be sure to not con­taminate electrical components with metal filings. A
grounding terminal is provided next to the discon­nect switch for an incoming ground wire connection.
Wire types and sizes must be selected according to
the National Electrical Code and all local codes and
restrictions. Refer to the input current and voltage as
listed on the nameplate on the enclosure door when
sizing the power wires. Only copper (Cu) wire rated
for 75°C (minimum) may be used for the power con­nections. The voltage tolerance is +10/-5% and
phase to phase voltage must not have an imbalance
greater than 5 VAC.

WARNING: Prevent electrical shocks.

Disconnect the incoming power supply to
the control panel before beginning installation.

FAILURE TO FOLLOW THESE INSTRUC­TIONS MAY RESULT IN DEATH OR
PROPERTY DAMAGE.

WARNING: Conduit grounds are not

adequate. A separate ground wire must be
attached to the ground lug provided in the enclo­sure to avoid potential safety hazards. FAILURE

TO FOLLOW THESE INSTRUCTIONS
COULD RESULT IN SERIOUS PERSONAL
INJURY, DEATH AND/OR PROPERTY
DAMAGE.

Manual LED will be on to indicate automatic opera­tion. The system must also be started by pressing the
START/STOP key. The Start/Stop LED will be on to
indicate the system is started.

During automatic pump operation, the pumps will

turn on or off based on the primary staging method.
If more pumps are required to meet the system
demand, they will stage on as required. When the
system demand is met, and the minimum pump run
timer is met, the pumps will destage until only one
pump is running. When there is no demand in the
system, the no flow shutdown alarm or event will
occur, shutting down the last running pump. During
this sequence, alarms may occur that shut down a
specific pump or all of the pumps. Various automatic
pump alternation methods may be used to alternate
the pump sequence at any time.

3.5 Alarms/Events

Some conditions can be defined as alarms or events,

while others are predefined to be alarms. See section

4.5 for alarm setup. Alarms are logged in the Alarm
Log and events are logged in the Events Log. See sec­tion 4.7 for logging. An alarm triggers the General
Alarm serial communications point and the A/V
Alarm relay output. An event will not trigger either
of these. See Appendix C for the serial communica­tions points list and section 4.3.8 for relay outputs
setup.

Some alarms or events will cause one or all of the

pumps to shut down. For Low System Pressure, the
user can define if the pumps will shut down or not.

All alarms or events require either a manual or auto-

matic reset. The RESET/SILENCE LED will flash
when a manual reset is required. Press the RESET key
to manually reset the system.

The values in parentheses in Table 11 are the default

values.

5.1 Battery

The system memory, including all user setup data, is

buffered by a 3V lithium battery while the unit is off.

When the controller begins to detect low voltage on

the battery, it will display an alarm to give the user

adequate time to replace it. If the battery is not

replaced, the user setup data may be lost when the

unit is powered down.

5.2 Signal Generator (analyzer) -

recommended

The following signal generators are recommended:

Beta calibrator Model 434 20mA signal analyzer,

Altek calibrator Model 334 4-20mA loop analyzer or

Druck USP III loop calibrator. The instruments may

be p u r c h a s e d f r o m a L o c a l Proc e s s C o n t r o l

Distributor. If some other instrument is used it must

float above ground, and preferably be battery pow-

ered.

5.3 Field Repair

Typical field repairs include replacing fuses, replacing

input/output modules, and assuring connections are

correct and secure. See Table 42 for a list of spare

parts.

5.6 Troubleshooting

Problem Solution

Service Mode LED Set the node switches on the controller to 0 and 0 and cycle power. Set the node switches
(blank screen) back to 1 and 1 and cycle power again.

Pump won’t start Check that the Start/Stop LED is on. Check that the pump status LEDs are blinking to
indicate that they are ready. Press the HELP key from the status screens to check the alarm
screen for any conditions that may prevent the pumps from running. If the RESET/
SILENCE LED is flashing, a manual reset of the system is required.

Pumps won’t stage on/off Check the Staging screen to see what the staging method is and what the next staging values
are. See section 3.4.4. Check the timers screen to be sure that the pump minimum run timer
is expired prior to destaging. See section 3.4.5.

No Flow Shutdown will Check the Timers screen to be sure that the NFSD minimum run time has expired. Only
not occur one pump must be running and the system pressure must be greater than the NFSD restart
pressure in order for NFSD to occur. See section 4.5.6.

Inaccurate amps, voltage Check that the calibration values printed on the label on the current transformer correspond
or power readings to the values shown in the Info screens. See section 5.5.

Section D —

Procedure for Field Balancing 70E/70M PRVs

The pressure reducing valves are factory set to the discharge
pressure on the unit nameplate. If adjustment is required,
check the following:

1. Does the desired system pressure correspond to
the pressure indicated on the unit nameplate?

2. Is the suction pressure equal to or higher than the
pressure indicated on the nameplate?

3. Is the demand (GPM) within the capacity indicated
on the nameplate?

4. Have the PRV’s been properly vented?

Any deviation from the above conditions will prevent
the unit from operating at the factory settings.

WARNING : Excessive Pressure
and Temperature Hazard

operate pump(s) at or near zero flow (closed dis­charge valve). Explosion could result. FAILURE

INJU RY, D E ATH, AN D / OR PR O P ERTY
DAMAGE.

To adjust the PRV, place the pump in manual opera­tion. See section 3.3.1. With the pump running,

Do not

slowly close the main gate valve downstream of the
discharge header, allowing a trickle of water to flow
through it. Read the system pressure on the display. It
should read 3 or 4 psi higher than the desired system
pressure. If not, remove the protective cap on the
pilot control valve and loosen the jam nut on the
adjusting stem of the PRV. Slowly turn the stem
clockwise to increase the delivery pressure and coun­ter clockwise to decrease pressure. (Note that a pilot
valve furnished for a 20 to 300 psi range will change
the main valve setting approximately 28 psi for each
full turn of the adjusting screw.) Set the screw so the
system display reads 3 to 4 psi higher than the desired
system pressure.

Open the gate valve fully. If feasible, draw between
50 to 80% of the designed pump capacity to recheck
the valve setting. The display should now read the
desired system pressure. Tighten jam nut and replace
cap.

Repeat the above procedure for all pump and valve
combinations as required.

The CV Flow Control Valve (opening speed control)
may require field adjustment if pressure hunting
occurs. Normal setting of the valve is from 4 to 7
turns open. Never open more than 8 turns.

Section E — Electrical Wiring and Control Settings
– Final Check List

___ 1. Does the feeder line voltage correspond to the unit

voltage? Check the unit nameplate.

WARNING: Electrical shock hazard.

Inspect all electrical connections prior to
powering the unit. Wiring connections must be
made by a qualified electrician in accordance with

open? They must never be completely closed during
normal operation. Throttle cock if check slamming is
noted.

____ 8. Is the piping properly supported so as to prevent

strains on the unit?

____ 9. Is the system, including the pumps and PRV’s purged

of debris and air?

CAUTION: Seal damage may occur. Do

not run pumps dry. Fill and vent the pump
volute prior to operation. FAILURE TO

FOLLOW THESE INSTRUCTIONS COULD

required.

 Confirm with the owner/installing contractor if there

will be any building automation or remote connec­tions required.

 Inspect and/or install any customer remote termina-

tions required.

 Make note of the design data supplied on the B&G

data label (inside of the control panel door)

 Use a volt meter to measure phase to phase voltage

on the entering power terminals at the disconnect.

 Compare available voltage to the nameplate data.

 Field install the supply water temperature sensor

(suction RTD)

 Locate the sensor and connection wiring coiled in the

panel (may have been coiled outside of the panel by
the factory). Uncoil and feed the sensor through the
back of the panel through a hole.

 Locate the sensor on the suction water supply pipe as

far from the header as practical.

 Tape to the piping in such a manner as to protect the

sensor and wiring from damage.

 Insulate the sensor with foam or fiberglass to prevent

sensing ambient temperature.

 Bladder storage tank
 Precharge the bladder storage tank before connecting

to the system. The air precharged should be 5 to 10
psi less than the system operating pressure.

 If the storage tank has already been installed and not

precharged, disconnect system piping from the tank
and equalize to atmospheric pressure, if an isolation
valve and drain are provided, use them.

 Apply air pressure to bladder through the air charg-

ing valve and pressurize to field conditions (equal to
the NFSD restart pressure or 5 to 10 psi below oper­ating pressure)

 Reconnect to the system piping

 Check for available suction water
 Open all supply and discharge valves.

 Close bypass valve if installed in the piping by others.
 Inspect the capillary tybing from the pump discharge

to the suction header.

 Open petcocks feeding the tubing.
 Ensure that the plastic tubing is not touching any

metal surface. Protect tuving with insulation to pre­vent abrasion where it may be touching metal.

 Use the pump vent plugs and or the vent cocks on the

main prv to prove available water for suction. Open a
faucet to create a demand for water on the system
pressure piping.

 Start the package
 Close the disconnect to apply power to the package.
