5.3 Pre-Configured Controller or Subsequent Starts The controller will briefly display the quick codes during start up but will then proceed to operator level 1. Note:- If the Quick Codes do not appear during start up this means that the controller has been re-configured in a deeper level of access, as stated above, and the Quick Codes may no longer be valid. The controller will power up in mode it was in prior to shutdown and you will see the display shown below. It is called the HOME display.

5.4.1 To Set The Required Temperature. From the HOME display:- Press ▲ to raise the setpoint Press ▼ to lower the setpoint The new setpoint is entered when the button is released and is indicated by a brief flash of the display. 5.4.2 Alarm Indication If an alarm occurs the red ALM beacon will flash, a scrolling message will give the source of the alarm and the alarm (relay) output will operate.
5.4.3 Auto/Manual/Off Mode Auto mode is the normal closed loop operation where the output is adjusted automatically by the controller in response to a change in the input signal. Manual mode means that the controller output power can be adjusted directly by the user. The input sensor is still connected and reading the PV but the control loop is open. The current level of the power output is adopted at the point of switch over from Auto to Manual. This is referred to as ‘Bumpless Transfer’.
5.4.4 To Select Manual Operation and Adjust the Output Power Press and hold ▼ and ▲ (Mode) together for more than 1 second. This can only be accessed from the HOME display. t+u 1. ‘Auto’ is shown in the upper display.

Mnemonic Scrolling Display and description Range THRES TIMER START THRESHOLD The timer will not run until the PV becomes in range of the value set by this parameter. This value can be changed when the timer is running. OFF or 1 to 3000 END.T TIMER END TYPE The action of the timer when it has timed out can be selected from Dwell (control continues at the setpoint), Off (control outputs turn off), SP2 (control at setpoint 2). Can be changed while the timer is running.
Mnemonic Scrolling Display and description Range The above three parameters are repeated for the next three program segments, i.e. TSP.2 (3 & 4), RMP.2 (3 & 4), DWEL.2 (3 & 4) This section applies to Alarms only If an alarm is not configured the parameters do not appear A1.--- - to A4.--- ALARM 1 (2, 3 or 4) SETPOINT sets the threshold value at which an alarm is detected. Up to four alarms are available and are only shown if configured.
Mnemonic Scrolling Display and description Range TD DERIVATIVE TIME determines how strongly the controller will react to the rate of change in the process value. It is used to prevent overshoot and undershoot and to restore the PV rapidly if there is a sudden change in demand. Off to 9999 seconds MR MANUAL RESET applies to a PD only controller i.e. the integral term is turned off.
Mnemonic Scrolling Display and description Range OP.HI OUTPUT HIGH limits the maximum heating power applied to the process or a minimum cooling output. +100% to OP.LO 1. (2 or 4) PLS. OUTPUT 1 (2 or AA) MINIMUM PULSE TIME to set the minimum on/off time for the output. Relay outputs are adjustable from 0.1 to 150 seconds. Logic outputs set to Auto = 55ms. Auto to 150.0 This section applies to current transformer input only. If the CT option is not configured the parameters do not appear LD.

This parameter selects the recipe to use.
6.4 Timer A timer can be configured to operate in four different modes. These can be selected in Level 2 using the ‘TM.CFG’ parameter as:• Dwell Timer • Delayed switch on timer • Soft start timer • Programmer if this has been ordered There are four operating states: 1. Run. This starts the timer 2. Hold. This stops the timer at the elapsed time. It will start again from the elapsed time when Run is selected again. 3. Reset. This sets the timer back to zero.
6.4.1 Timer Beacon Timer operation is indicated by a beacon labelled RUN: Timer Status Reset Run 6.4.2 RUN beacon Off On Timer Status Hold End RUN beacon Flashing Off Logic outputs The timer may be configured to operate an output when it is running or during the end state Note:• Power up - the ‘run’ state is selected if a Soft Start or Delay timer is configured or the ‘Reset’ state is selected if a Dwell timer is configured.
6.5 Dwell Timer A dwell timer (‘TI.CFG’ = ‘DWELL’) is used to control a process at a fixed temperature for a defined period. The action which occurs at the end of the timed period depends on the configuration of the ‘END.T’ parameter. End State e n d . t = Temp OFF SP1 Counting down Scrolling message SP2 dwel THRES = + n OFF TIMER RUNNING SP2 TIMER END OFF OFF Time RESET Digital Input RUN Digital O/P = t.run END Digital O/P = t.End Notes: 1.
6.6 Delayed Switch On Timer The timer is used to switch on the output power after a set time. When the timer status = run, the control output is off When the timer status = reset, the control output is controlling at SP1 Temperature SP1 (70) Time Scrolling Message TIMER RUNNING TIMER END Reset Run RESET Digital input RUN Digital O/P = t.run END Digital O/P = t.End 3216 User Guide Part No. HA027985ENG Issue 2.
6.7 Soft Start Timer The timer is used to start a process at reduced power and/or reduced setpoint. Timing starts at power up or when ‘Run’ is selected. When the Timer Status = Run, the controller power is limited by the soft start power limit parameter. The Soft Start setpoint is a threshold which, when exceeded, sets the timer to end. If the temperature is already above this threshold when the timer is set to run, the timer will time out immediately.

6.9 Programmer Model type CP is a controller which also contains a four segment setpoint programmer where each segment consists of a controlled rate ramp to a target setpoint followed by a dwell at that setpoint. These values can be set by the user. The program profile is shown in the diagram below. End Type Temp SP2 (servo from PV) SP2 (70) SP1 (20) DWEL.1 Starts at Current WSP Ramp to TSP1 at RMP1 DWEL.2 Ramp to TSP2 at RMP2 DWEL.3 Dwell DWEL.
Notes:Where steps are required, the ramp rate in the ramp/dwell pair should be set to ‘OFF’. 1. Where ramp/dwell pairs are not required, the ramp rate should be set to ‘OFF’ and the TSP the same as the preceding segment 2. TIMER END - when end type is SP2, Timer END does not occur until the ramp is complete or SP2 is achieved. It is more usual to use a DWELL end type (the default setting) 6.9.1 Power Cycling (Programmer) 6.9.
6.9.3 To Operate the Programmer Operation of the programmer is the same as the timer.
