1 – INSTRUMENT DESCRIPTION
1.1 – GENERAL DESCRIPTION
Model COC 30 is a microprocessor-based digital controller
designed to command ovens, particularly those used in
bakeries.
The instrument’s main feature is the possibility to have
separate control over the temperature and heating powers for
the TOP and FLOOR of the oven, as well as commanding the
oven’s lighting, extractor, the steamer and the steam injector.
The instrument can store up to 8 different cooking programmes
and a maximum of 7 relay outputs, up to 4 inputs for
thermocouples (J or K) or thermoresistances (Pt100) and 3
configurable digital inputs.
An internal clock makes it possible to programme the oven to
switch on automatically at the desired time, set cooking time
and, if desired, the automatic switching off of the oven.
The instrument also offers the possibility of having an RS485
serial
communication interface with MODBUS-RTU
communication protocol.
Other important functions present include: output power
limitation, automatic steam injection control, temperature
alarms, steamer temperature adjustment, automatic enabling
of extractor fan once cooking is terminated and configurable
auxiliary output.

FRONT PANEL DESCRIPTION
1 - P Key
: Used for accessing function parameter
programming and for confirming selections.
2 - DOWN (and AUX) Key
: Used to decrease the values to be
set and for parameter selection. If held down, it also makes it
possible to pass to the previous programme level to exit
programming mode.
When not in programming mode and if suitably programmed, it
allows control of the AUX output.
3 - UP (and SEL IN) Key
: Used to increase the values to be
set and for parameter selection. If held down, it also makes it
possible to pass to the previous programme level to exit
programming mode.
When not in programming mode, allows display of steam and
auxiliary probe temperatures.
4 - ON/OFF Key
: Used to switch the control device on (RUN
mode) or off (STAND-BY mode).
5 - PW LIM Key
: Used to enable/disable the power limiter.
6 - SEL PRG Key
: Used to access programme selection
