DESCRIPTION The 535 is a 1/4 DIN single loop process controller (SLC) designed to control any analog process variable (temperature, pressure, flow, level, etc.) in batch and continuous processes. The 535’s outstanding feature mix enables it to bring processes under control faster, more accurately and easily than competitive SLC’s, PLC, and PC based control systems. PowerTune® Functions PowerTune® Adaptive Tune modifies PID parameters to eliminate oscillation or drift when load changes occur. Adaptive tune works automatically without disturbing the process. The 535 is widely considered to be...

INPUT FUNCTIONS PROCESS VARIABLE Two universal inputs are available. Any input type may be field selected via jumper. Dual inputs may be used to: • Select input on demand • Switch upon failure • Derive a PV by subtracting (PV1 - PV2) • Derive a PV by adding (PV1 + PV2) • Derive a PV by averaging (PV1 + PV2)/2 • Select highest PV • Select lowest PV THERMOCOUPLES Transmitter Signals Input Range Milliamps DC A remote setpoint input is available. Signal is 0–20/4–20mAdc or 0–5/1–5Vdc (jumper selectable). Signal may be ratioed and biased. Eight local setpoints may be stored in memory. Setpoint...

OUTPUT FUNCTIONS On-Off Deadband: up to 15% of input range (in eng. units) OUTPUT MODULES The controller can have a total of four control outputs, alarm outputs and/or loop power modules installed. There are five types of output modules which can be configured to suit your particular application. The modules may be ordered factoryinstalled, or they may be installed in the field. Up to eight sets of PID values may be stored in memory and selected automatically, based on setpoint value, process Analog module: Either 0-20mA or 4-20mA (front panel selectable) into a load up to 1000ohms....

PROFILE CONTROL OPTION The 535 Profile Controller’s unique operator interface makes it simple to set up and operate while retaining powerful profile functions detailed below. The 535 can store 20 recipes, with a sample shown below. Recipes are selectable via front panel, contact inputs, or serial communications. Recipes may be linked to create extra-long recipes. 200 Recipes may be linked or repeated 99 times Ramps and soaks can be time or rate based Maximum 12 ramps and 12 soaks per recipe Guaranteed soak function insures soak set point has been achieved before soak segment starts Changes...

GENERAL SPECIFICATIONS CONTROLLER ARCHITECTURE The 535 Controller hardware can be configured as follows: Inputs: Two univeral process variable inputs are standard. Available options include: remote setpoint, slidewire feedback and 5 digital inputs. Outputs: Four outputs are available. See Ordering Information. RS-485 Communications: Available as option with any configuration. SERIAL COMMUNICATIONS Isolated serial communications is available using an RS-485 interface. Baud rates of up to 19,600 are selectable. The protocol supports CRC data checking. If communications are lost, a time-out...

SECURITY There are two levels of access: restricted and full. A configurable code is used to enter the full access level. Functions not available in the restricted level are configurable. Six different groups of parameters can be restricted. DUAL TIME BASE Two modes are available, Hours:Minutes or Minutes:Seconds PROFILE CONTROLLER OPTION When a 535 is specified as a profile controller, the SET PT (setpoint key) is replaced at the factory with a RUN key to facilitate operation. Setpoint access is available through use of the DISPLAY key. All functions are described in the manual supplement....
