Function
The SPECTOR control (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 SPECTOR
control via the ISO 11898 CAN bus
using the CANopen protocol.
The SPECTOR
control 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 SPECTOR control .
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.
