The Pulsar
Zenith 140 Intelligent Pump Controller is the ultimate
ultrasonic pump management system, offering unrivalled
performance. Using Pulsar’s proven non-contacting ultrasonic
technology it provides almost all known pumping routines in an
easy to use package.
By combining
advanced ultrasonic level measurement with the control and
monitoring of pumps and providing many other control functions,
it is possible to eliminate a PLC by using Zenith in a smaller
station. Significant capital and operation cost savings achieved
by using advanced truly unique patented "peak
tariff avoidance" (PTA) control software to
enables efficient control of pumps to optimise the use of
minimum cost electricity in a station or well. Zenith 140 has
been designed for use in applications where its control routines
(which include level to volume conversion, low cost economy
pumping and volumetric throughput calculation), provide real
ongoing cost benefits. Six control relays with seven digital
inputs offer energy saving and uniquely intelligent performance.
The high
level specification Zenith 140 system, incorporating back lit
LCD display, ac and dc supply capability in the one unit,
advanced pump control software routines, digita RS485 modbus
communication options it is available in an IP 65 fascia mount
mount configuration to suit panel fronts. With a maximum
projection of only 90mm into the control panel the Zenith 140
allows depth reductions and cost savings on MCC’s and control
cabinets.
Energy Saving:
Provides significant energy saving by maximising pump use during
low rate electricity cost periods, and limit pump use during
high cost tariff periods. There are 10 user definable periods,
which may be set at any time during the week, or set to a
recurring program.
Daylight
Saving Time: When selected, automatically corrects for
the relevant months of daylight saving time.
Digital
Inputs: 7 digital inputs allow multi purpose alarm and
control sequences for pump failure, other external inputs such
as rain gauge, or control inter locks may be used to monitor a
control event, manual override or reset, switches inhibit or
enable. Relevant information may be transmitted via an RS485
output to a common bus (options available) allowing change
commands to be actioned.
