PARAMETER DESCRIPTIONS
SP= Set Point- Desired Regulation Temperature
r0= Differential or Hysteresis
r1= Lower Set Point Limit
r2= Higher Set Point Limit
d0= Heating or Cooling Control-Regulation cycles only performed, neither
defrosting nor continuous cycles exist. Heating: To choose Heating Control:
Set d0=Ht (The output is active when TS1 (temperature of ambient probe) is
less than or equal to Set Point.)
TS1<=SP. It then disconnects when TS1>=SP-r0. Cooling: To choose
Cooling Control: Set d0=Co (The output is activated when TS1>=SP+r0.)
The display will switch off when TS1<=SP.
c0= Minimum Time Between Start to Stop.
c2= Load Status During Probe Error. In the event of an open or short circuited
probe, the unit will connect or disconnect the load as defined by this
parameter.
P1= Ambient Probe Calibration. Offset degrees to adjust ambient probe. If the
probe is not placed in the exact point that is to be measured, use a standard
thermometer and adjust the difference with parameter.
P5= Ambient Probe Type. (tcJ = Type J, tch = Type K, tcS = Type S.)
P6= Probe Response Rate. (0 = 8 sec, 1 = 4 sec, 2 = 2 sec, 3 = 1 sec.)
H5= Access to Probe Parameters. (The code is set to 0 from the factory.)
A0= Alarm 1 Hysteresis. The differential associated with A1 parameter.
A1= Alarm 1 Threshold. Number of degrees to the working set point that initiates
an alarm condition.
A2= Alarm 1 Exclusion Time. The amount of time the alarm is disabled from
instrument activation.
A3= Alarm 1 Configuration. Determines the alarm type: A3=0 alarm is disabled;
A3=1 alarm is activated if the ambient temperature >=SP+A1 and
deactivated if <+SP+A1-A0; A3=2 alarm is activated if the ambient
temperature <=SP+A1 and deactivated if >+SP+A1-A0.
A4= Alarm 2 Hysteresis. The differential associated with A5 parameter.
A5= Alarm 2 Threshold. Number of degrees to the working set point that initiates
an alarm condition.
A6= Alarm 2 Exclusion Time. The amount of time the alarm is disabled from
instrument activation.
A7= Alarm 2 Configuration. Determines the alarm type: A7=0 alarm is disabled;
A7=1 alarm is activated if the ambient temperature >=SP+A5 and
deactivated if <+SP+A5-A4; A7=2 alarm is activated if the ambient
temperature <=SP+A5 and deactivated if >+SP+A5-A4.

PARAMETER PROGRAMMING
Set Point (SP) is the only parameter the user can access without code
protection.
• Press SET. SP text will appear on the display.
• Press SET again. The real value is shown on the display.
• The value can be modified with the UP and DOWN arrows.
• Press SET to enter any new values.
• Press SET and DOWN at the same time to quit programming or wait one minute
and the display will automatically exit programming mode.
*The keyboard code can be reset to ZERO by turning off the controller and turning
it on again while keeping the SET key depressed.
Access to all code protected parameters.
• Press SET for 8 seconds. The access code value 00 is shown on the display.
(Unit comes with code set at 00 from factory).
• With the UP and DOWN arrows, code can be set to user needs.
• Press SET to enter the code. If code is correct, the first parameter label is shown
on the display (SP).
• Move to the desired parameter with the UP and DOWN keys.
• Press SET to view the value on the display.
• The value can be modified with the UP and DOWN arrows.
• Press SET to enter the value and exit to text parameter.
• Repeat until all necessary parameters are modified.
• Press SET and DOWN at the same time to quit programming or wait one minute
and the display will automatically exit programming mode.
BUZZER
In the event of alarm or error condition, the internal buzzer is activated. To silence
the buzzer, press and hold the SET and Down keys.
LED INDICATIONS
OUT This indicates the load is connected. The system waits for the
programmed minimum stop time of the load.
DISPLAY MESSAGES
In normal operation, the probe temperature will be shown on the display. In case of
alarm or error, the following messages will be shown:
• Er = Memory Error
• -- = Short-Circuit Probe Error (output determined by c2).
• oo = Open Probe Error (output determined by c2).
MAINTENANCE/REPAIR
After final installation of the TCS Series Digital Thermocouple Switch, no routine
maintenance is required. A periodic check of system calibration is recommended.
The devices are not field repairable and should be returned to the factory if
recalibration or other service is required. After first obtaining a Returned Goods
Authorization (RGA) number, send the material, freight prepaid, to the following
address. Please include a clear description of the problem plus any application
information available.
