WARNING

 The default set temperature on RDK-150-DC is 500 ° F. The controller will

start to heat the coil immediately after it is power up; so please make sure

the coil is placed in a secure place before power up.

 Disconnect the coil from the controller before you change any of the

parameter that is locked with pass code. Failure to do so may result in

coil heater damage from overheating.

 The coil heater should NOT be heated above 1000 ° F. Build-in alarm is

preset to 1000 ° F.

 When controller is turned off, the coil will stay at very high temperature for at

least 20 minutes. The heated coil is very dangerous: it will cause severe

burn if touched.

1. Introduction

This is a supplementary manual for the RDK-150-DC hot runner coil heater.

Only the advanced parameter settings will be covered in this manual. Please

check the main instruction manual for a quick guide. Advanced parameters are

divided into groups and can be accessed by entering a special access code.

Note 1. Set Temperature.

There are two ways to set the target temperature.

a. During the normal operation mode, press Λ or V once to switch the

display from process value (PV) to set value (SV, or target temperature).

The display will start to blink. Press Λ or V again to increase or decrease

the SV. When finished, wait 8 seconds and the settings will take effect

automatically (the display will stop blinking).

b. Press SET key once. Use >, Λ and V keys to enter code 0001. Press

SET key to confirm, then the display would be SV (Su). Press SET key

again to display the SV setting. Use >, Λ and V keys to enter the new SV

value and press SET to confirm. Press V key to change the display to

END. Then, press SET to exit. You can also ignore the steps after

confirmation of SV. The controller will return to normal operation mode

automatically if no key is pressed for 1 minute. The flow chart below

Note 2. Set alarm

The controller offers two alarms that can be set to turn on the buzzer at

specific temperatures. The first alarm is controlled by parameters AH1

and AL1. The initial setting will turn on the buzzer at 1000° F and off

when temperature drops below 999° F. The second alarm is controlled by

parameters AH2 and AL2. The second alarm is initially deactivated.

AH1 and AH2 are the temperatures to turn buzzer on; AL1 and AL2 are

the temperatures to turn buzzer off. When AH1(2) >AL1(2), the alarm is

set for absolute high alarm as shown in Figure 2 below. When AH1(2)

Note

<AL1(2), the alarm is set for absolute low alarm as shown in Figure 3

below. When AH1(2)=AL1(2), the alarm is deactivated.

Example, if AH1=250, AL1=249, when the temperature goes up to

250° F, the buzzer will be on; when the temperature drops down to

249° F, the buzzer will be off.

User can press the shift key (>) to temporarily mute the buzzer sound.

The alarm will buzz again if the alarm set temperature is reached again.

To permanently deactivate the alarm, set AH1=AL1 or AH2=AL2. Please

see flow chart in Figure 1 on how to set the value.
