The temperature difference is determined by the thermal conductivities, the
surface/mass ratio, and the ambient temperature. This temperature difference
between the tip of the sensor and the ambient temperature is proportional to
the coil temperature over the entire heating range. The correction is done by
multiplying the measured temperature by a coefficient PSL. The default value
is 1.00, which means no correction applied (see Table 4). For the 15.8 mm
coil and nail that we offer, PSL should be set to 1.28 if you want the
display to show the nail temperature.

Note: For coil and nail systems that are not provided by Auber, the user can
measure the surface temperature of a nail with a thermometer. 1) The nail
temperature can be measured by inserting a type K thermocouple with a fine
tip such as Auber's TC-K5 to the hole on the
reading from a single point infrared thermometer because it is very sensitive to
the measuring location, as shown in Figure 3. 2) Then, divide the coil
temperature on the controller by the nail temperature will give you the PSL
ratio. For example, if the surface measures 580F while as the controller reads
700°F, then, PSL = 700 / 580 = 1.20
HL is the parameter designed for setting a maximum controlling temperature.
This feature can mechanically cut off the heater once the coil temperature got
out of control; no matter it's due to an operation error or SSR failure. When
reading temperature is over this cut-off temperature, the built-in relay will be
activated to cut off the power to the coil immediately. This relay will be
deactivated when reading temperature is equal or lower than HL. If your set
temperature SV < HL, it has no effect on the control; but if your SV > HL, it will
heat up the coil above HL. Controller will cut off the power to the coil once it
reaches HL, which makes the coil cannot go higher than HL.
LL sets the low limit of the cooling off temperature. When the controller is
turned off, it will display "HOT" till the coil temperature cools down below the
temperature value set in LL. By factory default, LL = 100°F.
RST is the parameter to reset all parameter values back to factory settings.
6. Troubleshooting
1) Why the top LED show "-H-"?
No coil heater is plugged in, or no sensor is detected by the controller.
2) The coil can't reach the set temperature.
Before you connecting a coil to RKD-300B controller, please confirm the coil
has the same pin assignment as the controller.

If the coil temperature won't rise at all, stays at room temperature, it could be
that the coil's heater is not working, or the controller's output has failed.
If the coil can heat up to a temperature close to the set temperature but it won't
converge to the set point, check the output status indicator. If the indicator
remains blinking for a long time and won't turn solid, it is a PID parameter
tuning issue. If the indicator gradually turns to solid but the temperature still
won't reach the target, it's probably the heating element in the coil is not
powerful enough to overcome the heat loss.
3) The coil appears to be red hot (or much hotter) than the set temperature on
the controller.
If the tip of the temperature sensor in the coil heater (which is a type K
thermocouple) is not properly installed to in the coil, or if there is a short on the
thermocouple wires, the controller may read a low temperature than the true
temperature on the coil. This can result the coil overheating.
