Vertex VD 26 Series User manual

VERTEX VD 26 SERIES
USER MANUAL
The Vertex VD series Temperature Controllers are a “Low Cost” Digital alternative to analog
controllers, designed for use in simple applications where three term (PID) control is not required.It
comes from the factory with default settings making it an “on/off” controller but can be user configured to have
proportional action “proportional”. It has a single digital display allowing access to all the parameters including
the “Process Variable” and “Set Point”. It is fully configurable on input including PT100 (RTD).
There are three simple steps required to get you up and running:
1. Installation 2. Wiring 3. Commissioning
Installation
Select the panel cut-out sizes from the table depending on the Model VD controller you have chosen and install
the controller accordingly in your panel.

Wiring Precautions:
Before wiring please check the model you are using and establish the correct terminals you should use, by using
this information and double checking it against the label on the label on the controller.
1 Mains Power:
1.1 You can use any mains voltage between 90 and 264 Volts AC (50 or 60 Hz) or DC
1.2 You can also order the controllers with a “Low Voltage DC” input that will accept anything between 18
~ 32 Vac/dc for the mains power voltage.
1.3 The When using DC mains the input is not polarity sensitive
1.4 For Model VD2600 the mains voltage wiring goes on terminals 1 + 2
1.5 For Model VD2601 the mains voltage wiring goes on terminals 13 + 14
1.6 For Model VD2603/2604 the mains voltage wiring goes on terminals 19 + 20
2 Inputs will mostly be either thermocouple or RTD (PT100)
2.1 Firstly check on the box and case label to see if the controller you are installing is T/C meaning
thermocouple or PT100.
3 To Change the Input type on a VD series controller. (V4)
1. Press and hold the “set” key for 5 seconds.
2. The display will change and read “Pb”
3. Press and hold the “set” key for another 5 seconds.
4. The display will change and read “Type”
5. Use the “up” or “down” keys to select the input type you require.
6. Now press the “set” key once and the display will read “Type”
7. Now press the “set” key a few times until you reach the parameter “HiLt”.
8. Now use the up and down keys to set the input range high limit.
9. Typically these should be either 100, 200, 400, 600 etc etc to suit your application.
10. Now press the “set” key once again to move away from that parameter.
11. Now press the “set” and “down” keys together to revert to the normal position.
12. It is always a good idea after doing this to turn the power off and back on again and watch during the self
test that the correct input has been selected.
13. After turning the power on the display will flash and show the following
a. First the input type will be displayed.
b. Next the measurement units as in ºC or ºF
c. Next the range High limit will be displayed.
d. Lastly it will display the Range Low Limit. (This should always 0ºC)
4 Thermocouples have two wires only.
4.1 Points to check are that the thermocouple is connected on the correct terminals.
4.2 For Model VD2600 this is terminals 7 + 8 with the thermocouple +ve wire on terminal 7 and the –ve
wire is on terminal 8.
2
4.3 For Model VD2601 this is terminals 6 + 7 with the thermocouple +ve wire on terminal 7 and the –ve
wire is on terminal 6.

4.4 For Model VD2603/2604 this is terminals 9 + 10 with the thermocouple +ve wire on terminal 10 and
the –ve wire is on terminal 9.
4.5 If the temperature reads but responds in the reverse when testing, like when heating the display goes
down instead of up just swap these two wires around. This will not harm the controller in any way if it
is not correct.
5 PT100 (RTD) in most cases have three wires.
5.1 For Model VD2600 use terminals 7 + 8 + 9. The one color goes on terminal 9 and the two wires with
the same color go on terminals 7 + 8
5.2 For Model VD2601 use terminals 5 + 6 + 7. The one color goes on terminal 5 and the two wires with
the same color go on terminals 6 + 7
5.3 For Model VD2603/2604 use terminals 8 + 9 + 10. The one color goes on terminal 8 and the two wires
with the same color go on terminals 9 + 10
5.4 If you are using a PT100 (RTD) with only two wires, one wire will go on the terminal where the “one
color” described above goes, and the other wire one on either of the other two terminals used for PT100
inputs as described above and then you must bridge with a short piece of wire between these two
terminals that would have carried the same color wire as described above.
6 Control outputs can be either “relay” or “SSR”
6.1 Please check carefully on the box and label on the side of the controller to make sure what type of
output your controller has. Incorrectly wiring this may blow the output and you will be charged for
repairing it.
6.2 All controllers are “Relay” output as factory standard. To have SSR you must especially order them
with this option.
7 Relay output....If you are using a relay output controller use the normally open contact to switch
the power going to the contactor. On the VD2600/2601 these terminals are 11 + 12, VD2603/2604 terminals
17 + 18
7.1 Wiring this part of the circuit often involves other circuitry within the machine and someone with
general electrical knowledge should have a look at the circuit to decide how this should be connected.
7.2 If you are replacing an old controller of a different make, carefully identify each wire on the old
controller and then substitute them in the correct position on the new VERTEX model.
7.3 Extreme care should be taken if attempting to do this as experience shows that most times when it goes
wrong it was a simple swapping of a wire or two that causes the problem.
7.4 Always take time up front and write everything down clearly before disconnecting anything and take
extreme care not to swap or confuse wires. This should be done by someone with a good knowledge of
electrical wiring circuits.
8 SSR output...If you are using a SSR output controller you would simply wire two wires from the +ve and -
ve output terminals directly to the corresponding polarity terminal on the SSR. For Model VD2600 this will
be terminals 11 (-ve) and 12 (+ve) and for Model VD2601 terminals 11 (-ve) and 12 (+ ve) and Model
VD2603/2604 terminals 17 (+ve) and 18 (-ve)

8.1 If the controller is SSR output, it means the output signal is 24 Vdc. It is for use with SSR’s that have a

control signal input of 3 ~32 Vdc.
8.2 It will not work with SSR’s that have a control signal of 90~250 Vac.
8.3 If you have a SSR that works with 90~250 Vac you will need a relay output controller that will simply
switch the higher voltage signal feeding the Solid State Relay.
8.4 If you have any doubt at all consult your supplier who will assist in checking what exactly you
have or need.
9 Changing the display unit scale
9.1 This section explains how to change the unit display units that correspond to the linear input which as an
example may be 4~20 mA or 0~10 Vdc. It does not change the input signal calibration.
9.2 Press the SET and DOWN keys simultaneously for 5 seconds to access “LnLo” parameter. The display
will show first. Press the set key twice to get to
9.3 Adjust “LnLo” setting to correspond the low scale and after adjustment press key once to
access “LnHi” parameter.
9.4 Adjust “LnHi” setting to correspond the high scale and after adjustment press key once for
normal operation.
9.5 Note: When changing the engineering display units please ensure that the high limit to be found in the
PID level is set to that as well or the display will flash once the high limit in the PID level is exceeded.

10. Commissioning
Having correctly wired the unit you are now ready for the initial turn on.
1. Turn the power on and watch the display as the controller self tests and powers up.
2. You will be able to see which thermocouple type the unit is set up for.
3. Once the power up is completed you will be looking at the measured temperature.
4. This parameter is identified by the small “PV” light, which will be on.
5. You can now check and set the set point you require.
6. You access this parameter by pressing either the up or down keys once.
7. The “SV” light will now be on and you will be looking at the set value, which you should now set to
about 70% of your final operating temperature.
8. You do this in order to watch the temperature rise to the setpoint at which point the output identified by
light “C1” must turn off.
9. Once the “C1” light is off there should be no power going to the heating elements and the temperature
should stop rising. Should this not happen you must turn off the power and check your wiring.
10. The controller is supplied with a factory default making it an on/off controller. This means that the
temperature will rise up to the setpoint at which point it will switch off (“C1” off) and then drop a little
before the heating turns on again.
11. The controller is factory set with Pb=0 (on/off control mode). In this mode you can adjust a deadband
around the setpoint by changing the parameter. It works like this:

CODE DESCRIPTION RANGE Default
Control set point value LoLt －HiLt 500
Set point offset. This should always be left at 0 as any value here will
create an offset in control either above or below the “actual ” setpoint. It is
used as a “manual reset” when the controller is used in the proportional
control mode.
