SymCom 520CP-460 Voltage Monitor Product Description
SymCom’s Model 520CP-460 is a fully programmable, microcontroller-based,
current sensing device designed to monitor 3-phase pumps or systems
with ramp up times of 4 seconds or less. Applications include submersible
pumps, booster pumps, reverse osmosis systems, centrifugal pumps,
vertical turbine pumps, oil well pumps, chemical pumps or other similar
systems.
Three external current transformers must be utilized in conjunction with
the Model 520CP. The following 7 set points can be set and viewed from
the 3-digit alphanumeric LED: overcurrent trip point, undercurrent trip
point, current unbalance trip point, trip delay, rapid cycle timer (RD1),
overload restart delay (RD2), underload restart delay (RD3), number
of restarts after an overload, and number of restarts after an underload
fault. Last fault diagnostics is also viewable. When a harmful condition
is detected, the 520CP’s output relay is deactivated after the specified trip
delay. The output relay reactivates after the appropriate RD2 or RD3 timer
has expired. If the pump is started on a single-phase or a reverse-phase
condition, the Model 520CP deactivates its output relay in 0.5 seconds.
