TC4000 Digital High Capacity Outdoor Temperature Controller

MOUNTING THE CONTROLLER:

The following procedure should be used when installing the TC4000 temperature controller.

1. Choose an appropriate location considering the following:
a. Mounting location must provide strong, stable support.
b. Proximity to a suitable power supply.
c. Proximity to a means of disconnecting or switching equipment.
d. Proximity to heater load, in terms of sensors and monitoring. Thermocouples longer than 30m are not recommended.
e. The mounted location must provide easy access for the operator.
f. Appropriate clearances
Example: clearance to open enclosure door at least 90°, clearance to allow easy connection of power cords and sensors
g. Ambient operating temperature does not go beyond the range of:
32 °F to 104 °F (0 °C to 40 °C)
h. Humidity conditions within 20 – 85%, non-condensing temperatures

2. Mount the controller securely in the chosen location. All four mounting points must be used.
a. To mount from front (with the attached mounting brackets), simply hold the controller up to the mounting area, orient the mounting brackets as desired, and mark the new hole locations. Additional mounting hardware, suitable for the weight of the controller, may be required and is not included.
3. Supply power (inlet voltage) to be hardwired into controller.
4. As supplied, TC4000 controllers are NEMA 4X. To maintain this, all external connections must be installed with appropriate IP rated, liquid-tight fittings.
5. Ensure any heating elements connected to the controller are rated for the same voltage supplied to controller.
6. For protective grounding, connect suitably sized ground conductor at location marked in panel.

Enclosure Openings

For maximum flexibility, TC4000 controllers are sold with no openings already made in the enclosure. Holes for conduit and fittings may be made using a standard hole saw. Take care to avoid damaging components when making holes. Be sure to clear debris completely.

Power Input/Output Connection

The TC4000 is compatible with single- or 3-phase connections, and there are 2 voltage
ranges offered: 100-240 VAC and 480 VAC, clearly labeled on the controller. Do not
exceed the voltages listed on the controller!
Mains power must supply a Safety Ground connection to the controller.
Connect Mains power to the screw type terminal block.
Single-phase power is supported by supplying mains power to N/L2 (DB1-1) and L1 (DB1-
2).
3-phase Y or Delta is supported by supplying power to L1 (DB1-1), L2 (DB1-2), L3 (DB1-3) and N (DB1-4). This controller does not convert a Y feed into a Delta, or vice-versa.

WARNING
Each electrical supply conductor must be connected directly to its intended Input (for example, Zone 1 Input). Also, because controller power is provided through the input power connection for Zone 1, Zone 1 must be connected to an electrical feed. If Zone 1 loses power, all control functionality will stop.

Input Power is supplied through the modular terminal blocks. These are clearly labeled DB1-1, DB1-2, DB1-3, DB1-4 inside the controller, and the blocks are individually marked L1, L2, L3, N, Gnd as well. An allen wrench is required to insert connectors into the distribution block, and to disconnect. See Figure 2, above.

Heater output connections are spring-type connections. Zone 1 is marked TB-1 and Zone 2 (if applicable) is marked TB-2. All that is needed is a small screwdriver to push deeply into the terminal’s adjacent slot, to temporarily loosen each terminal clamp.

Each zone provides L1-L3, Neutral, and Ground (Gnd). The terminals are individually
marked L1, L2, and L3 as well. Connect the output Gnd wire directly to the terminal block
Gnd for that zone (Gnd terminal block is used as a pass-through). Customers using 3-
Phase Y connections should connect the output N wire directly to the terminal block N for
that zone (N terminal block is also used as a pass-through). The Neutral terminal block is
not switched, floating, and is provided as a pass-through connection for a 3-Phase Y
configuration.

Temperature Sensor Connection:
The TC4000 controller can directly accept thermocouples with mini-connectors. Supported thermocouples are (J, K). The sensor type must be set in the controller. Be sure to observe correct polarity when wiring thermocouples.

Sensor Placement:
Place the temperature sensor tip between the surfaces to be heated and the heater to be controlled. The tip must be placed in a location which best reflects the application. Depending on the object’s size and shape, there may be spots that are warmer or colder due to different thermal transfer parameters. If all areas of the object must reach a minimum temperature, then place the sensor tip on the coldest spot. If the temperature of any area of the object cannot go above the controller’s set point, then place the sensor tip on the hottest spot. If a temperature differential is allowable, then place the tip on an area where the temperature is between the hottest and coldest.

AL – Automatic reset Alarm – When the temperature extends past the High Limit Alarm, the alarm automatically disengages.
AL. n – Latched Alarm – When the temperature extends past the High Limit Alarm, the alarm display will remain engaged until it is manually reset. To manually reset the alarm, press and hold both the U and P buttons for 5 seconds.
AL.A – Acknowledgeable alarm – While the temperature is extends past the High Limit Alarm, the alarm can be acknowledged and disengaged by pressing and holding both the U and P buttons for 5 seconds. The alarm will automatically reset when the temperature returns to within the High Limit Alarm if it is not acknowledged prior.

Glossary

Alarm Output that trips when a certain condition is reached, for example, a defined
temperature. Note that the TC4000 only provides visual alarm capability, on the
controller display.

Control output Output that controls the process and is switched on and off as needed.
Hysteresis In the context of ON/OFF control of a heating system, Process Value (PV) must
exceed Setpoint Value (SV) by a certain quantity before the controller switches the
heater off, and PV must fall below SV by a certain quantity before the heater is turned
on. In each of these two cases, “certain quantity” could be equal or different,
depending on how the controller is set.

ON/OFF Control process based on full-power activation and deactivation of the output. Also called “Bang/Bang” or “Hysteresis” control. See “Hysteresis.”
– This type of control is not intelligent, and is not very accurate, but is simple, effective,
and controls how often ON/OFF switchings of the output happen. Minimizing how often
ON/OFF switchings happen minimizes component wear and tear.

Overshoot Situation in which Process Value exceeds Setpoint Value because the control action stopped too late. The ON/OFF controls have an overshoot greater than the PID controls.

Process Value / PV The value that the process variable (temperature, valve opening, etc.) has at that moment.

Sensor Device that translates physical phenomena (such as change in resistance based on
temperature) into electrical signals that can be measured and processed by the controller

Setpoint Value / SV The value that the process variable (temperature, valve opening, etc.) has to reach and maintain.

Thermocouple Sensor that transmits an electrical signal of a few millivolts. Cannot be tested for galvanic continuity. It needs specially designed extension cables.

Undershoot Situation in which Process Value does not reach Setpoint Value because the control action stopped too soon.

PROBLEM	SOLUTION(S)
Controller does not turn on

Verify that the controller and heaters are connected to proper voltage, according to
product identification labels.
Controllers’ fuse blown – check with multimeter and replace.

Does not heat|

Verify heater is connected to proper voltage. The identification label located on the
power cord displays the heater’s voltage requirement.
Using an ohm meter, check to see if there is a resistance reading (not an open circuit) in
the heater.
Many special heater plugs require special crimping tools. Ensure good connection
between the heater wiring, plug and input receptacle.
Use a Volt-Ohm meter to check the outlet receptacle.

Circuit breaker is tripping|

Validate that the circuit breaker is capable of handling the Amp requirement of heater.
The identification label located on the power cord displays the heater’s amperage
requirement.
Examine heater and cord for any damage.

Something has lightly
spilled on exterior or interior
of heater|

Apply any general household cleaner, that does not contain any silicone rubber
dissolving type ingredients, with a clean cloth fabric. Do not connect any heater to a
TC4000 that is not clean and in good repair.

Controller is heating to an
incorrect Setpoint
Temperature|

Controller will attempt to provide power to the heater whenever the PV is less than SV. If
thermocouple is not exposed to heater, the controller will operate at 100% in an attempt
to reach SV.

Controller Error Codes|

If these error messages occur, contact Briskheat® for service.
EPr—If the controller displays EPr, this error message will disappear automatically. If
this error message occurs multiple times, please contact your Briskheat® representative
for service. Replace sensor. If problem still exists contact Briskheat® for service.
