Control
Fully programmable PID or ON/OFF with adjustable hysteresis can be configured by the user.
PID Level Control
In addition to the standard PID with autotune function, PID level control allows the user to select up to four groups of PID control parameters ensuring optimum control is achieved over a wide range of setpoints. The transition temperature from one group to the next is programmable. Level PID control may be switched off if it is not required.
Alarms
Up to two low cost alarms may be specified and configured by the user to act as deviation or process alarms. They may also be used as programme end or time signal outputs.
Inputs
A wide range of thermocouple and resistance thermometer inputs can be specified.
Outputs
Relay, SSR and current outputs are available.
Heating/Cooling Control Action
Heating/Cooling control action is available with self tuning. A choice of control signals is available for both heating and cooling outputs.
Contact Inputs
They may be controlled externally using the optional contact inputs for RESET and RUN. Using an external timer or PLC, remote operation is possible.
Programming
They can be programmed for up to 8 segments. Each segment is either a ramp or a dwell. It is possible to have two programmes as well as linking the first programme to the second.
Programme End or Time Signal Output
If a contact output has not been specified as a temperature alarm, it is possible to provide an end of programme signal and/or a time signal (event). When a time signal is specified, it may be programmed to occur during a specified segment or over a number of segments.

Fixed Setpoint Control
In addition to the programme control function, a fixed dwell setpoint may be selected. The process is kept at a constant temperature until it is reset or advanced to the next segment. This is useful where the process can for example be reduced in temperature until the next batch is in place without reducing the temperature to ambient. This can save valuable time.
Process Value Bias
This option allows the measured object temperature to be offset on the display to compensate for errors due to difficulties in correct placement of the sensor.
Wait Zone Function
The programmable ‘waiting zone’ prevents the progress of the programme into the next segment until the process value is with the zone. This ensures that the product is soaked at temperature for the complete duration of the dwell segment.
Retransmission Output
An analogue output may be specified as a retransmission signal of process value, set value, deviation or as a control output.
Process Value Start
The PV Start function measures the application temperature and automatically starts the process from this value.
Data Security
Non volatile memory and set data lock prevents loss or inadvertent change of data due to power failure or incorrect operation.
Supply
These instruments are supplied with a 85/264V AC supply.
