1.1
Purpose of Manual
This manual describes the operation of the
Technologic
®
Constant Speed Pump Controller for
control of constant speed pump systems.
The control panel consists of an operator interface
panel (OIP), a disconnect switch, control transformer,
motor starters, motor branch circuit protection
including fuses or circuit breakers and thermal over-
loads, a 24VDC power supply, and terminal blocks
for customer connections.

Safety Alert Symbol
SAFETY INSTRUCTION
This safely alert symbol will be used in this manu-
al 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
®
Constant Speed Pump Controller
should have a safety instruction decal (part #
S11550) located on the front of the enclosure near
the disconnect switch. If the decal is missing or illegi-
ble 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 trouble-
shoot 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
disconnect switch is off. Turn off and lock out the
incoming power prior to troubleshooting or perform-
ing 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 instal-
lation information. Even when the Pumps 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 devic-
es include the use of properly sized and located pres-
sure relief valves, compression tanks, pressure con-
trols, 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 flu-
ids. This will be prevented by installing properly
sized and located pressure relief valves and com-
pression 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 contami-
nation 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.
