6.3. Controller power supply
Use the pins according to table below, considering the set version:
6.4. Recommendations of IEC60364 standard
a) Install overload protectors in the controller supply.
b) Install transient suppressors – suppressor filter RC – in the circuit to increase the service life of the
controller relay. See connection instructions of the filter on the previous page.
c) The sensor cables may be together, but not in the same conduit where the power supply of the
controller and/or of the loads passes through.
a) Cut out the panel plate (Image V - item 13) where the controller shall be fastened, with sizes
X = 71±0.5 mm and Y = 29±0.5 mm;
b) Remove side locks (Image VII - item 13): to do that, compress the central elliptical part (with the Full
Gauge Controls logo) and displace the locks backwards;
c) Introduce the controller in the notch made on the panel, inwards;
d) Place the locks again and then displace them until they compress into the panel, fastening the
controller to the housing (see arrow indication in Image VII - item 13);
e) Perform the electric installation as described in item 6;
f) Adjust the parameters as described in item 8.
ATTENTION: for installations requiring liquid tight sealing, the notch sizes for the controller
installation should be no more than 70.5x29mm. The side locks should be fastened so that they
press the sealing rubber avoiding infiltration between the notch and the controller.
Protector vinyl - Image VIII (item 13)
It protects the controller when installed at a site subject to water spills, such as refrigerated counters.
This adhesive vinyl is supplied with the instrument in the package.
IMPORTANT: Make the application only after completing the electrical connections.
a) Retreat the side locks (Image VII - item 13);
b) Remove the protective film from the adhesive vinyl face;
c) Apply the vinyl over the entire upper part, bending the flaps, as indicated by the arrows - Image VIII
(item 13);
d) Reinstall the locks.
NOTE: The vinyl is transparent, allowing visualization of the wiring system of the instrument.

8.3. Basic operations
8.3.1. Adjusting setpoint (desired temperature)
Hold the key / down for 2 seconds until the message[SET,]. is displayed. The adjusted control
temperature will be displayed when the key is released.
Use the keys<or>to change the value and then press / to save.
The desired temperature can also be changed in the quick access menu, (see map on item 8.1) or by
function [,F01] item 8.5.
8.3.2. Manual defrost
<por 4
down for 4 seconds. Press the key
8.3.3. Function lock
To unlock, turn the controller off and then turn it on again with the key held down. Keep the key held
down until[LOC,] is displayed. The message [OFF,] will be displayed when the key is released.
8.3.4. Control functions shutdown
The manual defrost is performed through the quick access menu ( ;) or by holding the key
;(quick touch) until the message [defr](led @flashing) is
displayed, and then press the key/(quick touch) to select. The message [defr][On,,](led
@on) will then be displayed.
To manually stop the defrosting, press the key ;(quick touch) until the message [defr](led
@flashing) is displayed. Press the key/(quick touch) to select. The message [defr][OFF,](led
@off) will then be displayed.
For safety reasons, the controller has a feature to allow functions to be locked. When this configuration
is active, the setpoint and other parameters are protected from undue changes. However, the
parameters can be viewed. Under this condition, the message [LOC,]will be displayed when trying to
change those values. To lock the functions you first need to adjust the parameter “[,F19] - Time for
function lock” to a value greater than 14 (below 15, [no,,]is displayed and it means that function
lock is not allowed). Select using the key ;,(quick touch), and then press /(quick touch). Then
keep > held down until [LOC,]is displayed. The message [On,,]will be displayed upon releasing
the key.
>
When the control functions are turned off, the controller starts to operate as a temperature indicator only
and the output relay turns off.
The way to turn off the control functions depends on the configuration of the parameter “[,F20]- Turn
off of the control functions”:
[,,,0]-Does not allow the turning off the control functions.
[,,,1]-Allows shutdown the control functions only if the functions are not locked.
[,,,2]-Allows shutdown the control functions even if the functions are locked. Using the key ;(quick
touch), select , and then press/(quick touch) to confirm.
Then, the message [ctrl][Off,] will be displayed. At this moment the temperature display will
alternate with the message[OFF,].
To turn the control functions back on, follow the same procedure used to turn them off, selecting with the
key ;(quick touch), . The message[ctrl][On,,] will be displayed as soon as the user presses
the key /.
NOTE: When the control functions are turned on again, the will keep following
the functions “[,f08]- Minimum output switched off time" and “[,f11]- Initial state when
turning the device on".
Press > (quick touch) to view the status and the time already elapsed. This way the controller will
display the stage of the current process, and the following messages may be shown on the display:
[----]- control off
[del,]- initial delay
[rEFr]- refrigeration
[Hot,]- heating
[dEFr]- defrost
Holding the < key down or also via the quick access menu (see item 8) will cause the message
[rEg,] to be displayed and the minimum and maximum temperatures to be recorded.
For erasing the current minimum and maximum values, press the ;key (quick touch) until the
message[CrEg] is displayed. Press /to confirm.
NOTE: These records are not stored in the internal datalogger and in the case of a power cut, the data
will be lost.
