Parameter Programming
The parameters are organized into 6 programming menus (COn, dEF, PrO, ALA,
HAC, and Ini) (HAC is only accessible when H11 = yes).
• Press the Set key for 8 seconds until 0 is displayed.
• Use the Up and Down arrows to reach the assigned security code
(factory setting for this code is 0).
• Press the Set key to accept the code.
• Use the Up and Down Arrows to select programming menu to enter.
• Press the Set key to reach the parameters under each programming
menu.
• Use the Up and Down Arrows to scroll through the parameters.
• Press the Set key to view the value of the parameters.
• Use the Up and Down Arrows to change the values of the parameters.
• Press the Set key to save the changes.
• Press the Set and Down Arrow to go back to the programming menu selection.
• Press the Set and Down Arrow a second time to exit.
Date Setup
• Access the Data Parameter (dAt) in the Initial Setup Menu.
• Press the Set key once to display the day (dXX).
• Press and hold the Set button for 8 seconds will cause the digits to flash and
allow the value to be changed.
• Use the Up or Down arrow to adjust the value for the day.
• Press and hold the Set button for 8 seconds to store the value (Pro will flash
when the value has been stored).
• Use the Up or Down arrows to switch from day (dxx) to month (nxx) or year
(yxx).
• Follow the same steps to adjust the month and year values.
Factory Default
• Go to H0 menu in the Initial Setup Menu.
• Adjust value to 1 for two output models or 2 for three output models.
• Press the Set key for 8 seconds.
• Press the Set key and Down Arrow simultaneously to exit menu.
Manual Default
Press the key for 8 seconds to activate/deactivate defrost cycle.
Continuous Cold Cycle
Press the Down key for 8 seconds to activate or deactivate a continuous cold cycle.
(CON will flash upon starting cycle and COF will flash upon completion of cold
cycle).
Resetting Keypad Security Code
Press the Set key during power up will reset the security code to 0.
Alarm Validation
Pressing the Down Arrow and the Set Key simultaneously will acknowledge an
alarm condition. The Alarm indicator and the buzzer will turn off after
acknowledging the alarm condition.
On/Off Lights
If one of the relays is set up to control a light, pressing the button for 3 seconds
will turn on or off the light.
LED Indicators
Indicates that the Compressor is engaged. It will blink when there is a
call for the compressor to turn on during minimum compressor stoppage.
Indicates defrost cycle is active.
Indicates that the Fan in engaged.
Indicates an error or Alarm or error condition.
HACCP Indicates that a HACCP event is being recorded.
Display Messages
In normal operation the probe temperature will be displayed. The display blinks
when waiting for a parameter to be saved or when there is an error saving a
parameter to memory. The following messages can also appear:
Err Memory Reading Error
ERP1, ERP2 Probe Error (check wiring or replace probe)
Eri Internal Parameter Error (factory default programming)
ALH High Temperature Alarm
ALL Low Temperature Alarm
ALE External Alarm Condition
AEH High Temperature and External Alarm
AEL Low Temperature and External Alarm
ooo Open Probe Error
--- Short Circuited Probe Error
DON Defrosting Activated
DOF Defrosting Finished
CON Continuous Cold Cycle Activated
COF Continuous Cold Cycle Finished
-d- Defrosting Cycle
During Probe error, the compressor will be cycled according to parameters c2 and
c3. Manual defrosting and manual continuous cold cycle operations can be
activated.
During memory error, the compressor will be cycled 5 minutes on and 5 minutes
off. Manual defrosting and manual continuous cold cycle operations can not be
activated.
HACCP
If this option is activated, the digital temperature switch can register up to 5 alarms
which could be high, low, or blackout. These alarms can be seen in the menu
registry of alarms (HAC).
This first value that appears is the number of registered alarms. Afterwards, for
each alarm (if any have occurred), the value of the temperature and time the alarm
occurred will be displayed. Once the alarm returns to normal state, the temperature
will be recorded along with the amount of time it took to return to this temperature
will be displayed.
When the elapsed time is shown, it will appear as xxd for the number of days.
Pressing the Up arrow will display xxH for the number of hours, followed by xxn for
the number of minutes. Pressing the Up and Down Arrows together for 2 seconds
will delete the current record being displayed. If the Up and Down arrows are
pressed for 2 seconds while in the HAC menu, all of the records will be erased.
Defrosting Cycles
The amount time between defrost can be based off the total time that the
instrument is on or it can be limited to the amount of time the compressor is
running. The first defrost will be performed at the hour of the day set with d3 and
the following cycles will occur in intervals of d8 after the initial defrost.
Intelligent Defrost
By turning on the intelligent defrost, the time between defrost will vary. This time is
only counted if the evaporator temperature is below the value of d15.
Selecting d13 = JuP, some of the defrosts may be skipped. After a defrost, the next
defrost(s) will be skipped based on the value of JdF. JdF is initially 0 and
increments if a defrost ends before a time d16*d2, otherwise it is decremented until
the value is 0. Maximum value for JdF is 3. After JdF = 3, if the next defrost ends
before d16*d2, JdF will be set to 1. Otherwise, JdF will be set to 0.
Selecting d13 - CiC, the defrosting cycle may vary. If a defrost ends before d16*d2,
then the time between defrosts is incremented d17 minutes, otherwise it is
decremented d17 minutes. The initial and minimum value for the time between
defrost is set by parameter d8. The number of time that the time between defrost
has been incremented can be viewed in parameter JdF.
Communication Connector
The communication connector can be used with the TS2-K to read or write the
parameter configuration to the Series TSX3. The connector can also be used with
a TS485 module to communicate with a computer or other device.
MAINTENANCE
After final installation of the Series TSX3 Digital Temperature Switch, no routine
maintenance is required. Clean the surface of the display controller with a soft and
damp cloth. Never use abrasive detergents, petrol, alcohol or solvents. Upon final
installation of the TSX3 Temperature Digital Controller, no routine maintenance is
required. A periodic check of the system calibration is recommended. The Series
TSX3 is not field serviceable and should be returned if repair is needed (field repair
should not be attempted and may void warranty). Be sure to include a brief
description of the problem plus any relevant application notes. Contact customer
service to receive a return goods authorization number before shipping.
