Termal TCS Series Instruction Sheet

Series TCS Thermocouple Switch

Monitor and Control

Monitor and control temperature in heating and cooling applications with
the Series TCS Thermocouple Switch. The Series TCS offers a wide
temperature range, two selectable alarm sets, and an internal buzzer
indicating alarm condition or error. The user can define set point,
heating/cooling regulation, cycle time, alarm configuration, load status, and
ambient probe adjustment. The thermocouple switch features password
protection and error/alarm messaging. Temperature and output status is

indicated on the bright red LED display. Use
the configuration key (sold separately) to
quickly program multiple units. The Series
TCS includes a fitting clip for panel
mounting, gasket, rear terminal cover and

instruction manual.

Installation

NOTE: Unit must be mounted away from vibration, impacts, water and corrosive gases.

 Cut hole in panel 2.80 x 1.14 inches (71 x 29 mm).
 Apply silicone (or rubber gasket) around the perimeter of the hole to prevent leakage.
 Insert unit into hole of panel.
 Slide removable fitting clips onto unit from the back until secure to panel.
 Remove back cover to wire unit.
 Wiring diagram is displayed on the top of the unit.

(Note: PROBE CABLE LENGTH MUST NOT EXCEED 238 ft. DO NOT INSTALL PROBE CABLE NEAR POWER CABLES).

 Replace cover once wiring is complete.

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 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.
