About this Installation & Operating Manual
This Installation & Operating Manual is a short instruction booklet containing important information on
function, installation, electrical connection and bringing into service.
Additional documents
The equipment specification EP - 370 (SPECTORcontrol) is part of this Installation & Operating Manual.
This description is stored in the equipment along with other documents.
Definition of terms
3-component controller
Large, temporary spikes in steam consumption cause the water in the pressurised system to boil and
effervesce, resulting in abnormally high readings by the level electrode.
To correct this error, both the water level and the steam and feedwater flowrate are measured, and the
difference is used to determine an appropriate quality factor. This factor allows you to assess the impact
of this difference (steam flowrate - feedwater flowrate) on the measured level signal.
Creep flow
Creep flow means that low flowrates are not measured during flowrate measurement. Creep flow is
caused by convection when the valve is closed.
Usage for the intended purpose
The SPECTORcontrol is used for controlling, viewing and setting parameters of GESTRA CANopen devices.
In combination with SPECTORconnect devices, it is used for visual display and status analysis with a
gateway functionality.
As well as GESTRA CANopen devices, it can also be connected to equipment from other manufacturers,
if approved by GESTRA, and integrated in the plant system.
IT security and rules for the use of Ethernet devices
The plant operator is responsible for the security of his/her IT network and must take appropriate action
to protect equipment, systems and components from unauthorised access.
Pay attention to the following instructions when using Ethernet devices in your system:
■Do not connect equipment, systems or components to an open network such as the internet without
adequate protection.
■To fully protect a PLC runtime system on a control system that is accessible via the internet, the use
of common security mechanisms such as firewalls and VPN access is absolutely essential.
■Restrict access to all components to authorised persons only.
■Always change default factory-set passwords before bringing into service for the first time!
■Deploy defence in depth mechanisms in your plant security, to restrict access and control to individu-
al products and networks.
Improper use
There is a danger of death due to explosion if the equipment is used in potentially explosive atmos-
pheres. Do not use the equipment in potentially explosive atmospheres.

Cutout threshold
If the control point is below the cutout threshold during pump control, the control point = 0.
This prevents the pump from constantly switching on and off.
Continuous blowdown
As the boiler water begins to evaporate, the concentration of non-volatile total dissolved solids (TDS) left
behind in the boiler increases over time as a function of steam consumption. If the TDS concentration
exceeds the limit defined by the boiler manufacturer, foaming and priming occurs as the density of the
boiler water increases, resulting in a carry-over of solids with vapour into steam lines and superheaters.
The consequences are adverse effects on reliability and severe damage to steam generating units and
pipes. To keep the TDS concentration within admissible limits, a certain portion of boiler water must be
removed continuously or periodically (by means of a continuous blowdown valve) and fresh feedwater
must be added to the boiler feed to compensate for the water lost through blowdown.
To determine the TDS in the boiler water, its electrical conductivity is measured in μS/cm, although
some countries also use ppm (parts per million) as the unit of measurement.
Conversion 1 µS/cm = 0.5 ppm.
Intermittent boiler blowdown
During the evaporation process, fine sludge is deposited on heating surfaces and on the floor of the
steam generating unit. This sludge is caused by adding oxygen-scavenging agents, for example. As the
sludge prevents the transfer of heat, the boiler walls can become dangerously overheated.
Intermittent blowdown is achieved by the abrupt opening of the intermittent blowdown valve.
The resulting suction effect occurs only at the moment the valve is first opened. The opening time
should therefore not exceed about 3 seconds. Longer opening times result in a loss of water.
Time-based pulse/interval actuation of the intermittent blowdown valve optimises the removal of sludge
from the boiler. The interval between intermittent blowdown pulses can be set, as can the blowdown
time.
For large boilers, repeated intermittent blowdown pulses may be required. In this mode, you can then
set the repetition and interval between pulses.
Operating position of the continuous blowdown valve
To keep the TDS within the desired limits, it is common practice for the continuous blowdown valve to
remove a certain amount of water from the boiler. This means that the valve must be permanently open
during operation, so that this amount of water can be discharged (valve in operating position).
This operating position can be adjusted accordingly. For the corresponding amount of boiler blowdown,
refer to the capacity charts of the continuous blowdown valve.
Compensation for steam bubbles (conductivity control)
The presence of steam bubbles can lead to greatly fluctuating conductivity readings. An attenuator will
damp the oscillations in the measurements.
Switching hysteresis (conductivity control)
If the controller is configured as 2-position controller, the valve will OPEN if there is a positive deviation
(X > w). The conductivity must then decrease until it reaches a new valve that is lower than the setpoint
minus the adjusted hysteresis. After this, the valve is moved into the Closed or Operating position,
depending on your settings.

Definition of terms
Standby mode (conductivity control)
To prevent water losses, continuous blowdown control and automated intermittent blowdown (if ena-
bled) can be disabled in standby mode or when the burner is switched off. The continuous blowdown
valve moves to CLOSED position, triggered by an external control command. The MIN/MAX limits and
monitoring function remain active in standby mode.
After the equipment has switched back to normal operation, the continuous blowdown valve is
moved into the OPERATING or control position. In addition, an intermittent blowdown pulse is
triggered, based on your settings.
Temperature compensation (conductivity control)
The electrical conductivity of water changes as the temperature falls or rises. To obtain meaningful
readings, it is therefore necessary to base the measurements on the reference temperature of 25°C,
and to correct the measured conductivity using a temperature coefficient.
Switching is no longer possible in the SPECTORconnect, TK Linear is the only option.
TK (Linear)
To ensure the reading is based on 25°C, set the TK between 0 and 3.0 % per °C (the default is
2.1 % per °C). This ensures linear temperature compensation of the reading over the entire measur-
ing range. This method is usually applied for steam generating units operating at a constant service
pressure. When the TK is set and the service pressure has been reached, use a calibrated conductiv-
ity meter to measure the conductivity of the boiler water, and compare the reading with the indicated
conductivity value. If the reading differs from the indicated conductivity, change the TK setting until
they tally.
TK (standard)
Since the relationship between conductivity and temperature is not linear over a larger temperature
range, various conditioning agents and different basic conductivities were used to establish empirical
conductivity/temperature curves. These curves are stored as standard curves and can be used for
temperature compensation. TK (STANDARD) is suitable for steam generating units operating with var-
iable pressure, i.e. that do not have a fixed working pressure (e.g. low load 10 bar, full load 15 bar).
TK (AUTO)
With this method, a plotted, installation-specific conductivity/ temperature curve is used for tempera-
ture compensation. This curve is plotted during the heating process and stored as an Auto curve. The
TK (AUTO) method is particularly suitable for steam generating units operating with variable pressure.
Cell constant and correction factor (conductivity control)
The geometric variable (cell constant) of the conductivity electrode is taken into account when calcu-
lating the conductivity. However, this constant may change during operation, e.g. due to soiling of the
measuring electrode. Deviations can be corrected by changing the correction factor. If the correction
factor is too high, a warning is displayed and the electrode must be cleaned.
Flushing the continuous blowdown valve
The continuous blowdown valve can be flushed automatically to prevent it from sticking. For this, the
continuous blowdown valve is actuated at intervals and opened for a certain time. After the flushing
time, the valve is moved into the OPERATING position or into the required control position.

Important notes
Function
The SPECTORcontrol (SC) is a control, display and operating panel with integrated programmable logic
controller (PLC) for CANopen devices.
In addition to GESTRA equipment such as conductive and capacitance level electrodes, temperature
limiters and conductivity electrodes, you can also connect equipment from other manufacturers, such
as Jumo CANTransP/T, and incorporate it in the overall system.
Data are exchanged between CANopen devices and the SPECTORcontrol via the ISO 11898 CAN bus
using the CANopen protocol.
The SPECTORcontrol periodically determines the current parameter settings and values of the CAN-
open devices. These are available for viewing as soon as the associated node ID has been set or allo-
cated. After this, connected equipment can be set and allocated directly on the SPECTORcontrol.
The individual inputs can be flexibly allocated to the various CAN nodes. However, the allocation of the
I/O module is dictated by the selected layout and cannot be changed. After a restart, the equipment is
in the initializing phase for approx. 10 seconds. After this, it shows up-to-the-minute readings of the
CAN nodes.
The system can process digital signals and analogue values, and allows you to establish alarm and
switching limits for them. These signals can be switched directly on the controller or further processed
by the logic and calculation functions, for example. Next, the signals are transmitted once again via
a digital or analogue output (IPO model). These signals can be used to accomplish various switching
tasks.
Clear, unambiguous signal names allow them to be allocated quickly in the system. Any cryptic desig-
nations can be replaced by the name of the equipment or the place of installation, for example, “LRG
16-41” can become “Boiler feedwater conductivity”. The maximum number of characters is 30. This
name is then used universally as key identifier. This is advantageous in large installations, where not
only boiler data but also liquid levels in feedwater and condensate tanks are recorded.

Safety note
The equipment may only be installed and brought into service by qualified and competent staff.
Retrofitting and maintenance work may only be performed by authorised staff who have achieved a
recognised level of competence through specific training.
The equipment specification EP - 370 (SPECTORcontrol) is part of this Installation & Operating Manual.
This description is stored in the equipment along with other documents.
Please pay attention to the safety notes in these documents!

Connecting the power supply of the Spectorcontrol
The SPECTORcontrol belongs to protection class 3. The unit is supplied with 24 VDC SELV (Safety Extra
Low Voltage). Remember to take the maximum breaking capacity of the fuse into consideration. The
power supply is not galvanically isolated. The 0V connection is directly at the housing potential.
Produce
the connection as follows:
■The supply cable must have a cross-section of 0.75mm² minimum and 2.5mm² maximum.
■A flexible lead or wire can be used for connection.
■Remember to take the power consumption into consideration.
■The use of a functional earth can prevent interference due to differences in potential.
The cross-section must not exceed 2.5mm2.
■The GND is connected directly to the housing potential.
The connector (female header with screw terminals) for connection is included in the product package
(WAGO 1757022).
In the control cabinet: Connecting the SPECTORcontrol
Supply voltage connection
The SPECTORcontrol unit, CANopen devices and WAGO I/O module are supplied with 24 V DC / ≥ 5 A.
5 A is the sum current of all CAN bus nodes. Please use a safety power supply unit with reliable electri-
cal isolation.
This power supply unit must be electrically isolated from dangerous live voltages and meet the require-
ments for double or reinforced insulation in accordance with one of the following standards:
DIN EN 50178, DIN EN 61010-1, DIN EN 60730-1 or DIN EN 60950.
Attention
■Do not use the bus power supply for GESTRA SPECTORbus control units for supplying
power to the SPECTORcontrol or connected equipment.
Attention
■In the event of reverse polarity and simultaneous connection
of another 0V connection, e.g. GND of the COM1 port, the fault
current flows via this 0V connection. If the housing is also not
connected securely to the 0V potential, the Ethernet panel or
external components may suffer irreparable damage!
■For a safe connection, make sure the two connecting cables are
joined close to the connector.

In the control cabinet: Connecting the SPECTORcontrol
WAGO I/O system 750 supply voltage
If the sum of the internal power consumption exceeds the sum current for bus modules, position a po-
tential feed terminal with bus power supply unit (750-613) upstream from the module where the admis-
sible sum current was exceeded.
Example:
In a node with a CAN bus coupler 750-337, 10 relay terminals (750-513) should be used. The power
consumption for this is 18 x 100 mA = 1800 mA. The coupler can provide 1650 mA for the bus modules.
Consequently, a potential feed terminal with bus power supply unit (750-613, max. 2 A output current)
must be added from the eighth terminal 750-513 of the node. In cases like this, a warning will tell you
of this situation when you are setting the parameters for the terminal.
You can check the configurations of the WAGO module using the free smartDESIGNER planning tool.
