Basic Operation 1 Introduction to the Controller and Manual 1.1 Using This Manual This manual aims to explain how to set up and operate the Eurotherm 3216CC series of controllers; it must be read in conjunction with the product main manual. Due to the complex nature of furnace or oven control the use of technical terms throughout this manual is unavoidable. Explanations of these terms can be found in the ‘Glossary of Terms’ at the back of this manual. This manual covers the operation of: 1.1.
Introduction 2 Basic Operation 2.1 Controller Layout (Home Display) Power Output Indicator Measured Temperature Setpoint Temperature Alarm Indicator Hold Indicator Remote Indicator Run Indicator (When configured) Scroll PageKey Key 2.2 Scroll Key Up Key Down Key Keys Page Key Scroll Key ACK Page + Scroll Arrow Keys The Page key is used to access level 2 when held down for 3 seconds. The Scroll key is used to scroll through the parameters.
Quick Start Guide 3 Quick Start Guide 3.1 Operation as a simple controller When switched on, the controller goes through a short test routine and then shows the measured temperature (PV = Process Value) in the upper part of the display, and below it, the set temperature (Set Point). 3.2 Changing the Set Point Press Up or Down to select the required SP.
Quick Start Guide When level 2 operations have been completed, the supervisor must return to Level 1 either manually or by ‘power cycling’, there is no time out function. To Return to Level 1 1. Press and hold the page Key 2. Press Down to select LEu 1 It is not necessary to enter a code when going from a higher level to a lower level when level 1 is selected; the display reverts to the home display (See Section 2.
Operating 4 Setting up the controller Before using the controller (or during its lifetime) certain parameters may have to be set, depending on specific requirements. To do this the controller must be set to supervisor level (Level 2) see section 3.4 4.1 Set Point Ramp Rate (3216CC only) To control the rate at which the temperature rises to sepoint, the SP.RATE function is used. Before setting the ramp rate, it is advisable to set the setpoint to a low value, preferably 0°C (see section 3.2).
Operating 4.3 Customer ID. A furnace or oven identification number can be entered if required. This maybe used to identify one of many units, for production or quality control systems. Press scroll until the display shows ID . Using the Up Down enter your own identification number. This can range from 1-9999. 4.4 Units Press scroll until the display shows units . Using the Up or Down select the required units.
Operating 5.2 Dwell Timer A dwell timer is used to control a process at a fixed temperature for a defined period. At the end of the time period the controller will switch off the output power to the elements. Press scroll until the display shows TM.CFG . Using the Up Down select Dwel When Dwell parameter is selected, the Timer resolution (TM.RES), Time duration (DWELL), Timer threshold (THRES) functions become available. Press scroll until the display shows TM.
Operating 5.4 Soft Start Timer The soft start timer is used to start a process at a reduced setpoint and power. The soft start setpoint is used as a threshold only and is not a control point.
Operating 6 Running a Timer Run. This starts the timer. Hold. This stops the timer at the elapsed time. It will start again from the elapsed time when Run is selected again. Reset. This sets the timer back to zero. It can be run again from this state. End cannot be set – it occurs automatically when the timer has counted down to zero. Acknowledge any timer after a timer has timed out using ACK function (see section 2.2) by pressing the simultaneously. 6.
Operating Running Dwell Timer with Ramp Rate Set the ramp rate as outlined in section 4.1 Set the dwell time as outlined in section 5.2 When the timer is set to run with a set ramp rate, the timer will not start to count down until the setpoint has been reached with the ramp, at which time the timer will begin time count down.
Operating 6.2 Delayed Switch On Timer Operation To RUN Timer Action Press and quickly release + To HOLD timer Press and quickly release + To switch off Timer / Cancel Press and Hold + for more than 1 second Press and Hold + for more than 1 second To return to home menu. After Resetting timer.
Operating Delay timer with ramp rate functions Timer Ended When ramp rate active To HOLD timer Press and quickly release + To switch off Timer / Cancel Press and Hold + for more than 1 second Press and quickly release + To re-RUN Timer Indicator – RUN = On - if ramp rate active Scrolling Text – Timer Running Indicator – RUN = Flashing Scrolling Display – Timer Hold Static Text - OFF Indicator – RUN = On - if ramp rate active Scrolling Display – None Static Text - OFF Indicator – RUN = On S
Operating Time Remaining The time remaining of any timer mode can be checked at any time while a timer is active. To view the time remaining, press scroll until the display shows T.REMN
Options 7 Options Because options can be ordered in a variety of combinations and for a variety of purposes, exact instructions are not given here. The full Eurotherm manual may be required to determine customer parameter settings. To reveal or hide parameters in the controller it is necessary to go into configuration modes and enter a security codes. Please consult Carbolite. 7.
Options 7.3 Comms Address Typically the comms address is set to 1, but this can be changed. In the case of RS485 and multiple instruments it is necessary to set different addresses. To change the address value access the level 2 list. In level 2 press the scroll key until the ADDR (ADDRESS) parameter is displayed. Use the Up Down to select the address value. 7.
