Specifications - Installation and Operating Instructions
Bulletin T-TS3
The Series TS3 Digital Temperature Switch is the ideal control for
on/off heating or cooling applications. This generation of controls has
field selectable engineering units and temperature probe types in order
to reduce the combination of parts that need to be stocked. A built in real
time clock is used for HACCP logging of temperature alarms caused by
temperatures outside of their set limits or loss of power. For refrigeration
applications, the defrost cycle can be initiated based on time or using the
front panel keys. For programming multiple units, the model TS2-K
configuration key can be used to quickly download parameter settings.
INSTALLATION
NOTE: Unit must be mounted away from vibration, impacts, water and
corrosive gases.
• Cut hold in panel 71 x 29 mm (2.80 x 1.14 in).
• Use the supplied gasket or apply silicone around the perimeter of the
hole to prevent leakage.
• Insert unit into hole from the front side of the panel.
• Slide the mounting bracket securely against the panel from the rear of
the unit.
• Wiring diagram is displayed on the top of the control.
Wiring
Avoid installing the temperature probe cables and the digital input wires
in close proximity of any power cables. If the length of the probe cables
is longer than 100 meters, a recalibration adjustment may be made
using the P1 parameter.

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 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 Probe Error (check wiring or replace probe)
Eri Internal Parameter Error (factory default programming)
ALH High Temperature Alarm
ALL Low Temperature 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 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.
Communication Connector
The communication connector can be used with the TS2-K to read or
write the parameter configuration to the Series TS3. The connector can
also be used with a TS485 module to communicate with a computer or
other device.
MAINTENANCE
Upon final installation of the Series TS3 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 TS3 Temperature
Digital Controller, no routine maintenance is required. A periodic check
of the system calibration is recommended. The Series TS3 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.
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.
