Vertex VT4826+ Instruction Manual

1. INTRODUCTION
This manual contains information for the installation, operation and tuning of your Vertex
VT26+ series FUZZY ENHANCED auto-tuning microprocessor based controller.
controllers carry a two-year factory warranty. The VERTEX microprocessor controllers are
FUZZY ENHANCED "proportional + integral + derivative" (PID) controllers that come in a
variety of standard DIN sizes. The input is configurable and allows selection of inputs between
thermocouples and RTD's. You can also have 4~20 and other linear inputs as an option to be
specified when ordering the controller. When ordering your controller you can choose between
Relay, SSR, Heat / Cool, 4~20 mA or other output signals. They have dual displays that show
the input (measured temperature) in the top digital display and the required set point in the lower.
They all come standard with 2 alarm relay outputs. The controller boasts a comprehensive range
of other features that include a ramp, soft start with power limiting, auto/manual function and
comes standard with two configurable alarms. The controllers can be switched to manual and
can work as "time based ratio out-put controllers" in the event of thermocouple or input failures
taking place. There are other options you can choose including "retransmission" of either the PV
or SV or RS485 communications.

Features:

 T/C, RTD selectable from front panel or as optional extra Linear Input.
 Heating output Relay, SSR or analog to be chosen when ordering
 Fuzzy enhanced PID Control.
 Auto / Manual Bumpless Transfer.
 Two alarm outputs.
 Standby and Latch mode can be combined with 8 different alarm functions.
 Ramp to set point and soak functions.
 Soft- start function.
 Universal power supply : 100~240VAC, 50/60Hz. Or as optional extra 24
Vdc/Vac
 PV or SV Retransmission (Cannot have retransmission and Cooling output
together.
 RS-485 communication port as optional extra.(MODBUS RTU)
 Input sampling time 0.1 sec
2. IN A HURRY
These Vertex temperature controllers, although quiet sophisticated, can be equally very
simple to use. In its simplest form, all you need to do is install it and get the wiring right,
(YOU MUST READ CONNECTIONS AND WIRING section) turn it on, check that the
thermocouple type it is correct, (during the self test it will display the input type), make
sure it is reading more or less the right temperature, that the heating elements actually get
hot when the "C1" light is on and away you go. No need for laboriously reading this
manual and changing and setting all the parameters....Just turn it on and when the system
