The manual defrost may also be activated/deactivated by holding down the key <for 4 seconds.
6.3.3. Functions lockdown
The use of the functions lockdown brings greater security to the operation of the instrument. When it is
active, the setpoint and other parameters can be visible to the user, but are protected against undue
changes (F36=2) or you can block changes of control functions and leave the adjustment of the setpoint
enabled (F36=1).
Using the key ; (short touch), access the function [LOC,] in the easy menu, confirm by pressing /
(short touch), then the message [no,,] will be displayed. After that keep the key > pressed for the
time configured for the functions lockdown (F37), until [LOC,] is displayed. The message [On,,]

until [LOC,] is displayed. Keep the key pressed for ten seconds and the message [OFF,] will be
shown on the display indicating the deactivation of the lockdown function when the key is released.
6.3.4. Control functions shutdown
The shutdown of the control functions allows the controller to operate only as a temperature indicator,
keeping the control outputs and alarms off. The use of this feature is enabled or disabled by the
shutdown function of the control functions (F38). When enabled, the control functions and alarms are
switched off ([CTRL][OFF,]) or on ([Ctrl][ON,,]) in the quick access menu through the
[Ctrl] option. When the control functions are off, the message [OFF,]is displayed alternating with
the temperature and other messages. Also is possible turn on/ turn off the control functions by pressing
the key ; for 5 seconds.
Note: By switched on again the control functions are counted the time defined in the instrument
energization delay and alarm inhibition time by temperature.
6.3.5. Visualization of Processes
To view the process and the time elapsed, press >(quick touch) or by the ;(Flatec) key pressing it
until the message appears. This way, the controller will display the current process status, and [Proc]
the following messages may appear on the display:
[dEL,]- Initial delay (delay in the instrument start-up)
[rEFr]- Cooling
[Hot,]- Heating
[dEFr]- Defrost
[drAi]- Drainage
[----]- Control functions off
6.3.6. Minimum and Maximum Temperature Record
Pressing down the<key or also via the quick access menu (see chapter 6), will cause the message
[rE9,] to be displayed, then the minimum and maximum temperatures recorded.
For erasing the current minimum and maximum values, hold down the ;key (quick touch) until the
message [CrE9] is displayed, then the message [CodE] will appear; enter the value [,123],
then confirm with the/key. If the code is correctly entered, the message [rSt,] will be displayed.
[rSt,]. This procedure keeps unauthorized users from erasing the minimum and maximum
temperature records.

F03 - Using Presets:
Allows configuration of the controller so as whether or not to use the presets:
[no,,]- No: If configured this way, the instrument will not use the preset values in the control routines.
For this purpose, the setpoint[SP,,] will be used, adjusted via the quick access menu. The control
differential to be used shall be the same as in preset [rc1,], F06 “OUT1 output control differential
([rc1,])”. The cooling time to be used shall be the same as in preset [rc1,], F07 “OUT1 output
cooling time ([rc1,])”. Defrost time to be used will be the same as in preset 1, F08 “OUT1 output
defrost time ([rc1,])”.
The value configured in [SP,,] may be adjusted between F13 “Minimum setpoint allowed to the end
user” and F14 “Maximum setpoint allowed to the end user”.
In this configuration, the controller will not indicate which preset is enabled.
[yEs,]- Yes: Selection of presets will be made through the quick access menu, in the same way as for
adjusting the setpoint. In this configuration, the controller will indicate in the display which preset is
enabled, [rc1,] or [rc2,]. If configured this way, in the control routines the instrument will use the
values of setpoint, control differential, cooling time and defrost time configured in the parameters table.
F04 - Output operating mode OUT1:
Selects the out1 output operating mode:
[,,,0]- Cooling
[,,,1]- Heating
F05 - Operation setpoint ( ): [Rc1,]
It is the reference value for temperature control, that is, the temperature to be maintained in a controlled
environment when preset ([rc1,]) is used.
F06 - Control differential (Hysteresis) ( ):[Rc1,]
It is the difference in temperature (hysteresis) between TURNING ON and OFF the cooling (or heating)
when recipe ([rc1,]) is used.
Example: One wants to control the temperature at 4.0 °C with a differential of 1.0 °C. Therefore, the
cooling is switched off at 4.0 °C and switched back on at 5.0 °C (4.0 + 1.0).

Description
F07 - Cooling time (interval between defrosts) ( ):[Rc1,]
Corresponds to the time the controller will act on cooling when preset ( ), is used; following this [Rc1,]
period, the controller enters the natural defrost process.
F08 - Defrost time ( ): [Rc1,]
It is the defrost duration time when preset ( ) is used. Within this period, the relay will remain off; [Rc1,]
following this period, the controller will then return to the cooling state.
F09 - Operation setpoint ( ): [Rc2,]
It is the reference value for temperature control, that is, the temperature to be maintained in a controlled
environment when preset ( ) is used.[Rc2,]
F10 - Control differential (Hysteresis) ([rc2,]):
It is the difference in temperature (hysteresis) between TURNING ON and OFF the cooling (or heating)
when preset ([rc2,]) is used.
Example: One wants to control the temperature at 4.0 °C with a differential of 1.0 °C. Therefore, the
cooling is switched off at 4.0 °C and switched back on at 5.0 °C (4.0 + 1.0).
F11 - Cooling time (interval between defrosts) ([rc2,]):
Corresponds to the time the controller will act on cooling when recipe ([rc2,]) is used; following this
period, the controller enters the natural defrost process.
F12 - Defrost time ([rc2,]):
It is the defrost duration time when preset ([rc2,]) is used. Within this period, the relay will remain off;
at the end of this period, the controller will return to the cooling state.
F13 - Minimum setpoint allowed to the end user:
Avoids regulation of excessively low setpoint temperatures by mistake.
F14 - Maximum setpoint allowed to the end user:
Avoids regulation of excessively high setpoint temperatures by mistake.
F15 - Minimum OUT1 output time on:
It is the minimum time the compressor will remain on, i.e. the time interval between the last start-up and
the next stop.
F16 - Minimum OUT1 output time off:
It is the minimum time the compressor will remain off, i.e. the time interval between the last stop and the
next start-up. It is used to relieve the discharge pressure and increase the service life of compressor.
F17 - Initial status when energizing the instrument:
It allows defrosting when controller is energized such as, for example, upon resuming of electric power
(in the event of power outage).
[,,,0]- Cooling
[,,,1]- Defrost
F18 - Temperature indication locked during defrost:
If [,F18] is enabled, the indication will only be released at the next cooling cycle after the temperature
reaches the “locked” value again, or after 15 minutes in cooling (as a safety measure).
F19 - Instrument energization delay:
This function being enabled, when the instrument is energized it only works as temperature indicator
remaining with the output off during the defined time. In installations with several units of equipment,
configuring different values for the delay time in the start-up of each instrument, it is possible to avoid
peaks of demand by activating the loads at different times.
This delay may be of the compressor or of defrost (when defrost is configured at the start).
Note: At its end, the count of minimum time of output off is started, if there is any.
F20 - Compressor status with the sensor damaged:
If the sensor is in short-circuited, off or out of the measure range, the compressor assumes the set status
in this function.
[,,,0]- Compressor off
[,,,1]- Compressor on
[,,,2]- Cycling according to times defined in [,F21] and [,F22]
Note: If in the heating mode, and in error, the output will be switched off.
F21 - Compressor time on in case of error:
F22 - Compressor time off in case of error:
These determine the minimum time the compressor will remain on/off, respectively, if the sensor is off or
out of the measure range.
F23 - Maximum Compressor on without reaching setpoint:
This is the maximum time the compressor may remain on without reaching the setpoint during the
cooling process for safety reasons. If this time is surpassed, the output is switched off and also the visual
alarm [ALrC] and the audible alarm (buzzer) will be activated. This function can be switched off by
setting it at the minimum value 0 [no,,].
Note: In this situation, the controller should be switched off and switched back on so as to continue with
the operation.
Note 2: If the OUT2 output is set up to work differently from the alarm, this will also be switched off for
safety reasons.
F24 - Low temperature alarm:
The temperature below which the instrument will indicate visual low temperature alarm [AtLo] and
the audible alarm (Buzzer). The differential for alarm shutdown is set at 0.1 °C/1 °F. This alarm
considers the temperature displayed, thus being influenced by the indication of temperature lockdown
during defrost [,F18].

F31 - Output on time in OUT2 alarm status:
F32 - Output off time in OUT2 alarm status:
Selects the cycling time in seconds of the alarm output when it is active. If any of those functions are set
with a value of [,,,0] the output will be permanently active.
F33 - Open door time for alarm:
If the door remains open for a time equal to, or greater than, the one configured in this parameter, the
controller will set off a visual open door alarm [AOPn] and the audible alarm (Buzzer).
The alarms are suspended upon the door closing. The audible alarm may be inhibited through the >
key (pressed for 2s). This function can be switched off by setting it at the minimum value 0 [no,,].
Note 1: In order for the open door alarm to operate, the function “Digital input operating mode” [,F30]
must be configured as open door contact.
The audible alarm is activated only if the buzzer is enabled in the function “Enable Buzzer (0-Disabled
/1-Enabled)” [,F29].
Note 2: If the function “Digital input operating mode” [,F30] is configured as open door contact, the
open door indication [OPEn] will be displayed every time the door is open, except for the cases of
alarm.
F34 - Operating mode of the digital filter:
[,,,0]- The filter acts both on the rise as on the decrease temperature.
[,,,1]- The filter acts only in the temperature rise ramp. When the temperature falls, your response
will be immediate.
F35 - Digital filter intensity applied to the sensor:
This filter has the purpose of simulating increase in thermal mass at the sensor thereby increasing its
response time (thermal inertia). The higher the value set in this function, the more time the sensor takes
to respond.
This function can be switched off by setting it at the minimum value 0[no,,].
F36 - Functions lockdown:
This allows and configures the functions lockdown.
[,,,0]- Do not allow the functions lockdown.
[,,,1]- Allow a partial lockdown where the control functions will be locked but the adjustment of the
setpoint, manual defrost, and maximum and minimum record are allowed.
[,,,2]- Allow the full lockdown, enabling only the manual defrost and maximum and minimum
record.
F37 - Time for functions lockdown:
Allow lockdown of control functions (see item 6.3.3).
[,,15] - [,,60] Defines the time in seconds for the controller to activate.
F38 - Control functions shutdown:
Allow control functions shutdown (see item 6.3.4).
[no,,]Disables the control functions shutdown.
[,,,1]Enables activation/deactivation of the control functions only if the functions are unlocked.

Example of connections for detecting open door and power outage:
This configuration may be used to detect power outage alarm (115/230 V AC) and also to detect that the
door has been left open (either one event).
In those configurations, the messages [AVoL] and [AOPn]are displayed alternately when alarm
event is detected (power outage or open door alarm).
For this purpose, the user may use the pushbuttons (not supplied) and a contactor or auxiliary contact
(not supplied) connected in series or in parallel, as shown in examples below:
Examples of connection for power outage detection:
This configuration may be used when MT-514e Faston is being energized by a 12/24 V DC
battery (common in vaccine refrigerators) and one wants to detect when a power outage occurred
(115/230 V AC). In this configuration, the message[AVoL] is displayed when alarm is detected for
power outage. To that end, the user may utilize a contactor or auxiliary contact (not supplied), where NC
(F30=[,,,3]) or NO (F30=[,,,4]) contacts are connected to the digital input and contacts A1 and
A2 (contactor coil) are connected to the power system, as shown in examples below:
[Athi]
[ALrC]
High temperature alarm.
Compressor reached maximum time on limit without reaching SP.
F25 - High temperature alarm:
The temperature above which the instrument indicates high visual temperature alarm [Athi] and the
audible alarm (Buzzer). The differential for alarm shutdown is set at 0.1 °C/1 °F. This alarm considers
the temperature displayed, thus being influenced by the indication of temperature lockdown during
defrost [,F18].
Note: For safety reasons, output OUT1 is switched off when the controller is configured for heating and
a high temperature alarm [athi] occurs, or when it is configured for cooling and a low temperature alarm
[atlo] occurs. For this reason you must configure the alarm threshold above (if heating) or below (if
cooling) the desired temperature (setpoint of output OUT1).
F26 - OUT2 output operating mode:
Selects the OUT2 output operating mode:
[,,,1]- Absolute extra-range alarm: Considers the values defined in[,F24]and[,F25]as
minimum and maximum values to activate the alarm output.
[,,,2]- Extra-range alarm relating to the setpoint: Considers the active preset setpoint [rc1,]
or [rc2,] and the absolute values defined in [,F24] and [,F25], i.e. the positive value of these
functions as minimum and maximum values to activate the alarm output.
For example:
Desired temperature[SP,,]: - 5 °C
Low temperature alarm [,F24]: 2 °C
High temperature alarm [,F25]: 2°C
Limits: ([SP,,] - [,F24] and [SP,,]+ [,F25]).
The low temperature alarm will be signaled at -7°C(-5 -2) and the high temperature alarm at -3°C(-5+2).
[,,,3] - Electric defrost (by resistance): Where only the OUT2 output is activated during the
defrost process.
[,,,4] - Hot gas defrost: Where the OUT1 and OUT2 compressor outputs are activated during the
defrost process.
[,,,5] - OUT2 output as OUT1 output NC: In this option, the OUT2 output is activated when OUT1
output is deactivated, irrespectively of the state (cooling/heating or defrost), except when the sensor is
in error [,F20].
Note: If the OUT2 output is configured to work differently from alarm, the indications of absolute alarm
are still visual (messages in the display) and audible (if the buzzer is enabled).
Note 2: If the OUT2 output is configured to work as defrost (electrical or hot gas), after elapsing of
defrost time a fixed 2-minute time period is counted for drainage. This time is necessary for the dripping,
i.e. for the last drops of water to run from the evaporator. Within this period, outputs OUT1 and OUT2
remain off.
F27 - Alarm inhibition time when energizing the controller:
This is the time during which the alarm remains off even under conditions of alarm during the instrument
start-up. This time will be counted after elapsing of the time configured in [,F19]. This function can be
switched off by setting it at the minimum value 0 [no,,].
F28 - Alarm inhibition time by temperature:
With this configuration active, the temperature will need to remain in the alarm condition during the
inhibition time set, for the alarm to be indicated. That way one can prevent alerts resulting from specific
temperature variations, and after defrost.
F29 - Enable buzzer (0-Disabled/1-Enabled):
Allows enabling and disabling of the internal buzzer for alarm signaling.
F30 - Digital input operating mode:
Selects the digital input operating mode.
[no,,]- Disabled
[,,,1]- Digital input: Open door (active at the contact closing)
[,,,2]- Digital input: Open door (active at the contact opening)
[,,,3]- Digital input: External alarm/power outage (active at the contact closing)
[,,,4]- Digital input: External alarm/power outage (active at the contact opening)
[,,,5]- Digital input: Open door and power outage (active at the contact closing)
[,,,6]- Digital input: Open door and power outage (active at the contact opening)
Examples of connection for detecting open door alarm:
This configuration may be used for the MT-514e Faston to detect whether the door has been left
open for a time above the value set up in “[,F33] - Time with open door to trigger alarm”. In this
configuration, the message [AOPn] is displayed when an open door alarm is detected. To that end, the
user may use the NO or NC pushbuttons (not supplied) connected to the digital input, as shown in
examples below:
