1.4 MANUAL OR AUTOMATIC CONTROL
The controller can be used in two modes:
Automatic mode - in which the output power is automatically adjusted to hold the
temperature at the required value. The controller normally operates in this mode.
Manual mode - in which the output is manually adjusted by the Operator. In this mode the
‘MAN’ light will be on.
One other mode is available:
Remote setpoint - The setpoint is generated as an input signal from a master 2000 series
controller. In this mode the REM light is on.

1.6 SELECTING SETPOINT 1 OR SETPOINT 2
The instrument has the facility to select two setpoints. This may be useful, for example, where
it is required to switch control between two different setpoints or to control in a standby
condition, thus avoiding the necessity to change the setpoint manually each time.
To Select Setpoint 1 orSetpoint 2
This may be done in two ways:-
1. By an external switch or relay contact wired to a digital input
2. Through the front panel using the SP list

1.7 RAMP DWELL FUNCTION
The ramp dwell function is selected by turning the setpoint rate limit parameter SPrr to a
value. It can be set to RUN in two ways:-
1. Through the front panel using the SP list
2. By an external switch or relay contact wired to a digital input configured for reset
(rset). When closed the program will reset. When open the program will run. To run
the program from the initial reset state, it is necessary to first close the switch then open
it.
The controller will then ramp from setpoint 1 to setpoint 2 at a rate set by the SPrr
parameter.
When the controller reaches setpoint 2 it can remain at this level for a timed period, using the
dwel parameter.
At the end of the dwell period the action of the controller is determined by the End Type
parameter End.t.
1.7.1 To Set up a Ramp/Time Program
Set setpoint 1 to the value at which to start the ramp. Set setpoint 2 to the value which you
wish to ramp to. This is described in the previous section.
Now press until SPrr is displayed

1.7.2 To Run the Program
In Full access level the Status of the program can be read as follows:-
A program may also be reset or run using an external switch contact if a digital input has been

1. During Ramp. After return of power, the working setpoint will servo to the current PV
value, and the ramp continues to SP2 followed by the timed dwell.
2. During Dwell. After return of power the working setpoint will servo to PV, the ramp
continues to SP2 followed by full programmed dwell. In effect this causes the program to
restart.
