JockeyXG Pump Controllers

FTA550E Series & FTA556E Series (Wye-Delta Open Transition)

Firetrol® FTA550E Series JockeyXG Pump Control­lers are intended for use with fi re pump systems. They
are used for pressure maintenance in fi re pump instal-
lations to prevent unnecessary operation of the main
fi re pump. FTA556E Series are basically the same as
the FTA550E Series except they utilize wye-delta open
transition starting instead of across the line starting.

Approvals — Firetrol Jockey Pump Controllers are listed

by Underwriters Laboratories, Inc., in accordance with
UL508A, Standard for Industrial Controls, and CSA,
Standard for Industrial Control Equipment (cUL). They
are built to meet or exceed the requirements of the ap­proving authorities as well as NEMA and the latest edition
of NFPA 70, National Electrical Code.

Enclosures — The standard enclosures are NEMA Type 2

(IEC IP22), drip-proof, for installation in areas protected
from direct sunlight with an ambient temperature above
41°F (5° C).

FTA550 Series Jockey Pump Controllers

The FTA550E Jockey Pump Controller utilizes across
the line, full voltage starting. Full voltage is applied to the
motor as soon as the controller is actuated, and the motor
supplies its rated torque. When using full voltage starting,
the power source must have suffi cient KVA capacity to
handle motor locked rotor current and prevent the line
voltage from dropping below acceptable levels.
FTA556E Jockey Pump Controllers utilize wye-delta
open transition starting. Upon a call to start the starting
contactor is engaged, after 2 seconds, the run contactor
is engaged, bringing the motor to full speed.
When the controller is actuated, either by a drop
in system pressure (in the “Auto” mode), or by placing
the HAND-OFF-AUTO switch in the “Hand” position, the
pump will start. In the “Auto” mode, the pump will con­tinue to run until the pressure returns to a normal level
and the minimum run timer has expired, whichever occurs
last. In the “Hand” mode, the pump will continue to run
until the HAND-OFF-AUTO selector switch is moved from
the “Hand” position.
The stainless steel pressure transducer is mounted
inside the enclosure and is piped to a fi tting on the bot-
tom of the enclosure.
