INTRODUCTION
Main Control Unit (MCU)
The primary monitoring and control
hardware for the Tanktronic system.
The unit can manage up to 4 x individual
tank sensors and 2 x Keraflo control
valves plus additional third party
devices.
S-Module
An expansion module that increases
Tanktronic’s operational capacity. Each
S-Module will allow 2 x control valves
to be added, plus additional third party
devices. Up to two S-Modules can be
joined to a single MCU.
Repeater Unit
Works as an interface extension to the
MCU, allowing the user to monitor and
control the Tanktronic system from
another location. The Repeater Unit
can be located up to 100m from the
water tank(s) and does not require a
separate power supply.
Battery Module
Provides a back-up power source to
the mains supply, providing up to two
days of normal operation before power
is expended. We strongly recommend
tting this module if the building
application is particularly dependant
on Tanktronic’s ‘Holiday Schedule’
function.

2. INSTALLING THE
SENSOR IN THE TANK
Allocate one sensor to
each tank. It is advisable
to label each sensor
(Sensor 1 for example)
and its corresponding
tank (Tank 1 for example)
prior to lowering the
sensor into the tank.
1. A 25mm hole should
be drilled in the top of
the tank, preferably
away from the water
inlet pipe.
2. Lower the sensor
into the tank so it is
suspended with the tip
of the sensor touching
the bottom of the tank.
Take care not to allow
debris to enter the
tank. It is suggested
that the tank is drained
down and chlorinated
before refilling.
3. A tapered rubber
bung is fitted to the
sensor cable to hold
the sensor in place
in the tank; slide this
bung down the cable
and force into the
hole through which
the sensor has been
lowered, securing the
cable in place.

of the control valve. If the closing speed
is too short, water hammer will be heard.
This must be avoided to prevent damage
to the pipe and system.
Turning the closing speed adjustment
screw clockwise will increase the delay.
If the control valve fails to close or does
not close quickly enough, the closing
speed adjustment screw should be turned
anti-clockwise to shorten the closure time.
Servicing and maintenance
No routine maintenance should be
necessary. If debris has entered the water
supply, isolate the supply to the control
valve assembly and inspect/clean as
appropriate.

d. DEVICES
Tanktronic allows third party devices
(alarms, valves, pumps etc) to be
switched on or off, based on water and
temperature levels in the tank(s).
Operation
Devices can be configured to be
controlled by either individual tanks or the
entire system.
The Main Control Unit features
2 x volt-free contact inputs (VFCI) and
4 x volt-free contact outputs (VFCO).
For electrical connection details see
page 15.

For Twin Tanks you
must identify the Pilot
Valve as common or
separate.
Adding a device to an
individual tank or system
Tanktronic provides a sensor and pilot as
two standard devices that can be added
to a tank. For other devices select:

30 COMMISSIONING 31COMMISSIONING
Device name Description & functionality Operation Interface Cong parameters (default value)
Kerao Pilot Normal inlet valve, as in default config. Opens when level drops below fill delay
level threshold, and closes when level reaches close level threshold, or sensor
not responding. (For twin tank shared inlet valves, both tanks are controlled
together.)
tank SOL shared (separate)
Generic Inlet Non-latching inlet valve, same as above except on VFCO. tank VFCO shared (separate)polarity (normally open)
Log Alarm Out Active if any alarms are in the log. system VFCO polarity (normally open)
Sys Alarm Out Active if any system alarms (mains off, sensor not responding, slave channel
not responding etc.)
system VFCO mains off (disabled) auto/manual reset (man)polarity
(normally open)
Tank Alarm Out Active if the relevant tank alarm threshold (level high/low or temperature high/
low) is exceeded. If shared, then checks both tanks, if system device then
checks all tanks.
tank or system VFCO threshold type (hi level) shared (separate) auto/manual
reset (man) fail-safe state (active) polarity (normally open)
Override Out For controlling safety override inlet valve, dump valve, pump set, etc. Similar
functionality to tank alarm output, it becomes active if the relevant tank
override threshold (level high/low or temperature high/low) is exceeded. If
shared, then checks both tanks, if system device then checks all tanks.
tank or system VFCO threshold type (hi level) shared (separate) auto/manual
reset (man) fail-safe state (active) polarity (normally open)
Lockout In Used for leak detectors, BMS override etc. If active, close inlet valves (but not
safety override valves). If shared, and tank is a twin, also close inlet valves on
twin. If alarmed, creates entry in alarm log.
tank or system VFCI shared (separate) alarmed (disabled) auto/manual reset
(man) fail-safe state (active) polarity (normally open)
Lockout Out Indicates lock-out state of tank (i.e. if lock-out input or manual lock is active).
If system device, then active if any tank locked out.

Select safe state in case of
failure (if required)
If the system stops responding,
choose here whether the device fail-safe
default is active or inactive.
• Active – System fails, device
switches to pre-set switching state
• Inactive – System fails, device
remains in current switching state
Polarity (if required)
Select the required contact idle state:
• Normally Closed – Open when active
• Normally Open – Closed when active

e. LEVEL OFFSET
NOTE: This step is only necessary if
either of the following points apply.
The sensor does not reach the bottom
of a tank.
Two or more tanks of different sizes are
being monitored and a common set of
readings is required for both tanks, for
example, a pair of balanced tanks with
a common discharge.

Level Offset can be set with the sensor
in position in the tank. Select from the
MAIN MENU screen:
Scroll through the options displayed and
then select:
Use the and buttons to set
the necessary Level Offset.
Exit to HOME screen.
The water level will now read the entered
offset when the sensor is out of water.
If the initial water reading was 1.56m and
an offset of 0.44m was entered, then the
resultant water level reading will be 2m.
NOTE: There is a slight delay to allow
the sensor to settle at a particular
depth before that level is displayed on
the screen. This is to prevent nuisance
readings caused by turbulent water.

f. HOLIDAY MODE
SET-UP
Tanktronic allows the user to set a
schedule of operation of the tanks at lower
level - typically during ‘holiday’ periods of
reduced activity.
Holiday levels
To set up holiday levels for each tank,
select from the MAIN MENU.
Then select:
Levels can now be set for the range of
settings listed above. Refer to diagram on
page 19.
NOTE: The alarm and over-ride levels
have ‘crossover’ behaviour to avoid
false triggers when Tanktronic switches
between ‘normal’ and ‘holiday’ modes.
When switching modes, Tanktronic
uses the normal high alarm and over-
ride levels and the holiday low alarm
and over-ride levels until the water
level reaches the new target band (i.e.
between close level and ll relay). This
assumes the holiday levels are always
set lower than normal levels.
Each tank can be set with its
own holiday level.
• Close level • Alarm level low
• Fill delay • Override level high
• Alarm level high • Override level low
