ABOUT THIS GUIDE, AUDIENCE AND CONCEPTS
This guide describes the equipment controller EC 531. The equipment controller can either be used
stand-alone or communicate values and conditions to a central SCADA system or a web based alarm
and monitoring solution like AquaWeb from Sulzer.
Installation guide There is a separate document Installation guide that describes how to physically install the pump
controller (printed document in the installation package, and also a PDF on www.sulzer.com).
Audience This guide is intended for system administrators and operators of EC 531 equipment controller.
Prerequisites This guide assumes that you already are acquainted with those pumps you are set to control and
have the sensors connected to EC 531.
The system administrator must also know and decide on the following:
1. The pump controller can either use an analog level-sensor, which measures the water level in the pit,
for precise control over start and stop levels, or it can use simple oat switches placed at start and
stop levels.
• Float switches can be used in addition to an analog level-sensor, as a backup, and as an
additional alarm input.
• An analog level-sensor has several advantages over oat switches: it is more robust
(cannot get stuck or be mechanically jammed); it is more accurate; it is more exible (the
start and stop levels can easily changed); you can get readings of the water level in the
pit, the inow, overow and the pump capacity; you can optimize the pump performance
in various ways, including exercising, alternative stop levels, tariff control etc.
• It is also possible to employ an alternative stop level, usually a lower level than normal,
that is effective once after a number of pump starts. This can be useful if it is desirable to
“completely” empty the pit once in a while.
2. You need to know if the pump(s) should be exercised in case of long idle periods. If the installation
has one or two pumps, you need to decide if the pumps should alternate.
3. If the electricity has daily varying tariffs, you must know the times of high / low tariffs.
4. You must know how overow will be measured: if it will be measured using both an overow detector
(to detect the start of the overow) and a level sensor (to measure the actual ow), you must know the
parameters (exponents and constants) to be entered as settings so that the overow can be accu-
rately calculated by the EC 531.
5. You need to know which alarm class, A-alarm or B-alarm (see Glossary and conventions), to assign
each alarm.
Reading guide For installation, see the separate document Installation guide, which covers EC 531. Before you
make any settings, or use the control panel, read chapter 1 Oiverview of the display symbols —it
describes the general functionality and the meaning and usage of the controls on the panel.
The system administrator must ensure that all settings according to chapter 2 Setup the EC 531 are
suitable for your application.
NOTE! The default settings are listed in the Installation guide

Text appearing and declaration in this guide
Text in italic is a description of text on the display or a description how you nd your way through
the menus by key strokes. Text in bold, is how you have to do a change of the settings in the EC 531
menu.
Most settings in chapter 2 only apply to the system administrator, but the following also apply to those
who operate the controller: language selection, date and time settings, units, backlight time-out,
buzzer, operator passcode, start / stop levels.
Glossary and conventions
To designate a menu item in a hierarchy, an angle bracket is used to separate the levels. Ex-
ample: Settings > System means the menu item you reach by rst choosing the menu item
Settings, which has a number of submenus, where you choose the menu item System.
Text in blue indicates a hypertext link. If you read this document on a computer, you can click on
the item, which will take you to the link destination.
Pump exercising: Long idle periods in a corrosive contaminated environment are not good
for pumps. As a countermeasure, they can be “exercised” at regular intervals, which will reduce
corrosion and other detrimental effects.
Alarm class: The alarm class can be either A-alarm or B-alarm. A-alarms are those that require
immediate action, so operational staff in the eld should be alerted regardless of the time of day.
B-alarms are less important, but should be taken care of during normal work hours.
Digital in: A signal that is either ON or OFF (high or low), where high is anything between 5 and
35 volts DC, and low is anything below 2 volts.
Digital output: A signal that is either ON or OFF. At ON condition output current is sourced
from the power supply and the output is high (~V+). At OFF condition the output is low but it
cannot serve as a drain function (no output current). Are typically connections to relays.
Analog output: Signal in the range 4-20 mA. Sourced from power supply.
Analog input: Eight analog inputs used for connecting sensors. Ain:1 to Ain:4 are 4-20mA in-
puts. Ain:5-Ain:6 are congurable for Pt100 and PTC. Ain:7-Ain:8 are congurable for or Pt100
and Leakage.
Pump reversing: The controller can reverse the pump if the necessary external equipment is
installed in the station. The controller can reverse the pumps on number of occasions, e.g. low
capacity, pump fail, fallen motor protector, over currents and after number of starts
RS 485 modules: Refer to surrounding units connected to the RS 485 bus, e.g. soft starters,
VFDs, and an energy meter.

1 OVERVIEW OF THE DISPLAY SYMBOLS
EC 531 is designed to control 1-2 pumps. It can operate a pump station stand alone and / or within
a surveillance system together with some communication equipment. For conguration and opera-
tor interaction, use the menus which can be selected using the arrow, Enter and Esc keys. With the
AquaProg software, conguration and back up of settings can be stored on a PC.
Add the 3G modem CA523 to create a full remote alarm and monitoring solution, together with an
AquaWeb rental contact or by any SCADA system.
This section will guide you through all the symbols on the display of EC 531.

1.1 EC 531 panel
The default screen (top-level view) of the display on the EC 531 dynamically shows the operating sta-
tus of the pumps and conditions in the pit, displaying just about everything you need to know about
the current situation. Figure 1-1 shows symbols and explains their meanings. The unit will always re-
vert to this view after 10 minutes of inactivity in any other view (such as showing menus or submenus).
In the submenus you can always return to the default screen by pressing ESC.

1.2 Symbols on the graphic display
There are several symbols in the EC 531 display which are described below.
Figure 1-2 Symbols on the display
The top screen appears differently depending if there is a level sensor in the system or not. There is
no level value presented if the pit is without a level sensor. If no analog (Ain1-4, preferred Ain1) input is
dedicated for Level sensor, the controller assumes there are Start / Stop oats. The start / stop oats
are animated and must have a dedicated input if they are to appear on the display.
1.2.1 Time and date
When an alarm occurs, this eld turns red for A-alarm or yellow for B-alarms and the alarm text is also
shown here. The time and date is no longer visible.

1.2.2 Level and the dynamic eld
If level sensor is installed on one of the analog inputs, the height of the level in the pit is present-
ed, shown with two decimal places, and by means of a visual water level indicator on the graphics
display. Level can be referenced from sea level (if set). If there is a high-level alarm setup and it gets
activated, the dynamic eld turn into red. If the system runs on oats, no level or visual water level
indicator will be shown on the display.
1.2.3 Outlet value on the display
Outow: After the controller has calculated the pump capacity, a value appears on the display when
the pump or pumps run. See the se c t i o n 3.1 Pump capacity calculation for information on how the
calculation is done and which parameters are necessary to set.
Outlet pressure: If there is an outlet pressure sensor installed, the value appears on the display. See
the section 3.1 Pump capacity calculation for information on how the calculation is done and which
parameters are necessary to set.

1.5 Power and alarm indicator
The two leftmost symbols on the panel are for power and alarm indication:
• A green light indicates that the unit is powered.
• The red alarm indicator ashes whenever there is an unacknowledged alarm, and the dis-
play tells the type of the alarm. When the alarm is acknowledged, the light turns steady
red, and remains so until the active alarm is remedied.
1.6 Menus and submenus, passcodes and personal alarm
The arrow keys on the key pad have different functions depending where in the menus you are. From
the top screen, the functions are following:
Key pad shortcuts

which can be made with
the arrow keys
Use the left / right buttons to choose the insertion point. Use the up / down buttons to increase / de-
crease a value or letter. Press Enter to enable editing of a value. Values and strings can also be altered
through the alphanumeric keyboard. Finish the editing by pressing enter.
You conrm an operation with the Enter button, or acknowledge an alarm. Pressing the Escape will
cancel operation and leave setting unchanged or return animated top screen.
Passcodes There are three security levels:
1. Daily operations, such as acknowledging an alarm or stopping a pump, do not require any pass-
code or authorization.
2. Operational settings, such as setting the start or stop levels for the pump, require a passcode at
the level of Operator; default 1.
3. Conguration settings that affect the basic functionality or access, such as the type of level sensor,
require a passcode at the level of System; default 2.
After entering a passcode a timer is started, all settings are unlocked until timer resets. The factory
default passcodes are 1 and 2 respectively, but the codes can be changed under the menu item
Settings > System. Whenever a passcode for Operator is requested, you may supply either the pass-
code for Operator or System.
Personal alarm When the pump station is manned, a personal alarm can be issued if the maintenance person hasn’t
shown activity within a certain period of time. For details about settings related to this, see section
4.1 Digital in: Personnel alarm and local mode (assigning Alarm type, Alarm delay and Max time to
reset), how to set up the digital input and digital output for staff in station.
After the specied Alarm delay, the assigned output is activated so a visual or audio signal can alert
the maintenance person that the alarm timer must be reset. If the alarm timer is not reset within Max
time to reset, a personal alarm is sent out.
NOTE! To reset the timer, just push any button on the control panel.
1.6.1 Status view
Status view is easy to access by pressing [left arrow] for pump 1 or [right arrow] for pump 2 on the key
pad. Status view shows Pump running time, Number of starts, Start / Stop level, Pump capacity,
Motor current, Motor power, Last pump capacity calculated value, Starts since last reverse, if the
pump is Blocked or not and Detailed status.

2 SETUP THE EC 531
Overview of settings
Every station will have its own unique conguration but the procedure to setup the station is similar.
This chapter will guide you through the basic settings in the EC 531. Make note that this does not
cover everything, you must take into account your prerequisites.
The menu item Settings has 14 submenus with a large number of settings that need to be entered by
the system administrator, although they all have default values. The notes below are a recommended
procedure to setup the EC 531.
2.1 Set general conguration, system, ID and communication settings
2.2 Set designated IO functions at DI, DO, AI and AO according to the electrical wiring drawing
2.3 Pump pit parameters and alarms
2.4 Set pump 1 and pump 2 settings and their alarms
2.5 Common P1-P2
2.6 Set log settings
2.7 Set up communications to surrounding units (VFD, soft starters (if used)
2.8 Set up cleaner, mixer or drain (if used)
Each of the 14 submenus under settings are described in separate tables in appendix.
To enter the settings area:
Press down arrow once and you are in the menus, continue to press down arrow to Settings, press
Enter.
All settings require a passcode for System except some settings under the submenu System and the
start / stop levels under submenus Pump 1 and Pump 2 which only require a passcode for Operator.
All the settings can be congured locally from the menus or by AquaProg. The advantage of Aqua-
Prog is you can save the conguration at your PC and easily restore the controller if needed.
2 .1 Set general conguration, system, ID and communication settings
Setup the language, System ID, units (metric or US units) by the menus:
• The topmost menu item System will be selected. Press Enter again.
• The topmost menu under System is Language. Press Enter and give passcode (de-
fault2) by using Up / Down arrows. Scroll to the language of your choice by using the Up
/ Down buttons.
• Select Station ID, Press Enter. Type in your station ID by using Up / Down arrows, re-
quired for AquaWeb or any other surveillance system.
• Select Date format, press Enter. Choose your date format.
• Set Date, Time, Units (Metric or US) and all other setting under this parameter.
• Set System alarms according to your preferences.
• Press Left arrow to return to Main menu; Settings. Scroll down to Communication.
• Set the Protocol of USB (Modbus RTU or TCP), cross reference (if used).
• Set the Protocol of Service port (DB9 in front).

* MUST for accurate pump capacity calculation
It is recommended to setup the Pit area under Station ow as this will give the best possible pump
calculations accuracy. These are also tied to Energy calculation, Pump capacity and Outlet calcula-
tions.
There are several alarms which can be set under Pit alarms. Each alarm is congurable to be A- or
B-alarms. Consult your drawings and verify which are important for your installation. Every alarm can
trigger the crash log, see section 3.7 for further information about crash log.
2.4 Set pump 1 and pump 2 settings and their alarms
Important parameters to congure for each pump:
Type of pump control
Running indication
Start / stop level
Pump alarms
Optional parameters: Pump curve

Pump 1 and pump 2:
Type of pump control:
• Pump disable
If using only one pump in the system; recommended to have pump 2 as disable
• ON / OFF control
A digital output starts the pump without any RS-485 communication to VFD or soft
starter
• VFD manuel speed
Start a VFD which has predened frequency
• VFD PID control
Start / stop pump with digital output and VFD controlled by 4-20mA analog output
from the controller
• VFD best efciency point
Require RS 485 communications to VFD
Select run indication:
• Any discrete source
Output signal or digital input
• Output signal
No return signal from the pump, just activated output signal from the relay contact
• Motor current
Current transformers connected to an analog input
• Fieldbus RS 485
RS 485 communication to / from VFD or soft starter
Start / Stop levels for each pump
Recommended to have different start levels if there are two pumps. Same stop level for two pumps is
ne.
Pump alarms
There are several pump alarms to setup. Each alarm is congurable to be A- or B-alarms. The rst
part, table 2-8 below, is to setup the types of alarm (A- or B), alarm delay and if the alarm shall trigger
the crash log.

Block pump on alarm
These alarms must be acknowledged on site or remotely to allow the pump to start again.
Hold pump on alarm
All the alarms here will block the pump when the alarm is active. When the criteria for the alarm have
returned to normal state, the pump starts again automatically.
2.5 Common P1–P2
To avoid possible station problems this option has many useful functions like, Pump exercising,
Pump reversing, Max number pumps running, Min relay intervals, Alternations and Pump block-
ing.
Figure 2-3 AquaProg view of common P1-P2
2.6 Set log settings and events
There are 16 congurable analog log channels on the EC 531. It is recommended to the use the log
channels in sequential order from channel 1, as having log channels disabled between active chan-
nels will cause unnecessary data trafc to the surveillance system.
The logs are kept in the controller for 15 days and the oldest will be deleted when the memory is full.
