Thissectionincludesinformationregardingtheinitialinspection, preparation for use, and storage instructions for the 465 controller.
Note: If the 465 controller is used in a manner not specified by nVentThermalManagement,theprotectionprovidedbythe controller may be impaired.
2.2Initial inspection
Inspect the shipping container for damage. If the shipping container or cushioning material is damaged, it should be kept until the contents of the shipment have been verified and the equipment has been checked mechanically and electrically. If the shipment is incomplete, there is mechanical damage, a defect, or the controller does not pass theelectricalperformancetests,notifythenearestnVentThermal Managementrepresentative.Iftheshippingcontainerisdamaged,or the cushioning material shows signs of stress, notify the carrier as well asyournVentThermalManagementrepresentative.Keeptheshipping materialsforthecarrier'sinspection.

During quickstart, the controller checks the current flow after a short period of time. If the current flow is below the detection limit, the user will be asked whether contactor mode should be activated or whether short heating cables should be used (which deactivates the current monitoring of the output).
Select Imperial or Metric units
The unit is automatically executing a connection check. It will check the heating cable connection, ambient sensor and pipe sensor connection. A connection of the unit to an external contactor needs to be confirmed by the user.
Warning:The465 controller can't monitor the load current and ground fault current in each cable segment when an external contactor is used. External ground fault protection must be provided using appropriateGFEPD.

Sensors Set-up

Setting up Sensors 1 and 2 is fully flexible. Assign each sensor to be a line or ambient sensor. Select if you want the circuit to remain on if the given sensor fails by clicking "Power On TS Fail". Select which sensor you would want to use for high limit cutout. Make sure Sensor 1 is connected to terminals S1 and .

Fine tune the individual sensor settings in the parameters setting menu.

Control Mode Setpoint

If only one sensor is used, leave the other sensor settings blank.
This allows selection of the type of algorithm to be used to maintain the setpoint temperature. Select Ambient On/Off, PASC (Proportional Ambient Sensing Control) or Line Sensing Control. If no ambient or line sensor was assigned, the corresponding control mode will be disabled.
This is the temperature that the controller uses to determine whether its output switch should be On or Off.

3.4.4Deadband

Purpose

Thedeadbandisawindowofdifferencebetweenthe measured control temperature and the desired control setpoint temperature and provides the decision to turn the output off or on

Setting/Range1°F to 8°F (1°C to 4°C)

FactoryDefault5°F (3°C)

3.4.5Minimum Expected Ambient Temperature
Purpose Thisistheminimumexpectedambienttemperaturewhich will be used to calculate the duty cycle for proportional ambient sensing control mode

3.4.11Temperature Condition Filter

Purpose Settimedelayfilterfortemperaturecondition

Setting/Range1 to 200seconds

FactoryDefault10 seconds

3.4.12High Ground Fault Current

Purpose

Thisallowstheusertosetthegroundfaultcurrent supervisory level. Exceeding this limit will trigger the supervisory event to indicate that a ground fault condition
existsintheheatingcablecircuit.Toprotectagainsttherisk of fire or shock, ground fault level should be set at the lowest level possible to allow normal operation of the cable.

Setting/Range20mAto200mA

FactoryDefault20mA

3.4.13Ground Fault Trip Level (HI GF Trip)

Purpose

Thisallowstheusertosetthegroundfaultcurrenttrip level. Exceeding this limit will result in the output switch being latched off and the ground fault level trip supervisory activated to indicate a ground fault condition.

Warning:FireHazard.Groundfaulttripsupervisorymust notbeignored.Topreventtheriskoffire,donotre-energize heating cables until the fault is identified and corrected.
