The final temperature for a segment is entered and the time required to reach that temperature and the FCS-23A does the rest, ensuring a linear increase or decrease. * Program start can be either manual, via the key pad or automatic, 2 seconds after power-on. * Either alarm ouput can be programmed to turn on at the end of the final segment as a `pattern end output'. * The SV display can be programmed to show either the setpoint value, the % output power or the time remaining for the current segment. Using one key, the user can toggle between all three displays. * The setpoint value displayed changes as the time increases for each segment, e.g. in the example on the left, halfway through segment 1, the setpoint value will be displayed as 250. This enables the user to judge the ramp linearity by comparing the SV with current PV. Loop Break Alarm This is a programmable alarm of temperature rise or fall against time. The time setting is 0 to 200 minutes and the temperature span is 0 to 100C (0.0 to 100.0C for ranges with a decimal point). If the PV does not rise by the span or greater within the set time after the output power reaches 100% (or does not fall by the span or greater within the set time after the output power falls to 0%), then the alarm contact closes. This can be used to check that: * mobile infra-red heaters are placed close enough to the target. * multiple element heaters are all functioning. Delayed Action Alarms Both alarm 1 and alarm 2 can be set as delayed types. The time is adjustable from 0 to 60 seconds (or 0 to 9999 seconds for infra-red input models). If short transient alarm conditions occur, they will be ignored, unless they exist for at least the set time. Main Setting Value Rising and Falling Rates Even when the ramp/dwell feature is not being used, the rising and falling rates can be independently programmed to ensure that the rise or fall is controlled linearly. This applies when the power is turned on, i.e. the first temperature rise and also if the setpoint is changed to another value. SM Function - Remote Memor y Access If this option is specified, then two of the seven memories can be selected using remote wiring. This is not just a remote setpoint selection, but also a selection of pre-programmed values for P,I,D, alarm 1 setting and the output high and low power limits for each memory. A 3-metre, 2-wire, flying-lead (supplied), is plugged into the back of the instrument for connection to remote switches, push-buttons, relay contacts, PLC outputs, etc. If the two wires are joined, memory number two is selected. If the FCS is set to memory number five, for example, using the front keypad, closing and opening the wires will toggle between memories and two and five.

If using extension cables, a third wire should be added from point C, one of the joins, as in the diagram above and all three wires should be the same gauge and length. If a simple link is added between terminals 9 and 10, in this case, no compension for lead length will be applied. * As there is no fuse inside the temperature controller, it is recommended that one is provided in the external wiring to the power supply terminals. * The sensor wires should not be run adjacent to an AC power supply or the wires to the power supply terminals. * When using the relay contact output version it is recommended to provide an auxiliary relay to protect the contacts of the temperature controller's built-in relay, even if the intended load capacity is smaller than that of the built-in contacts. * For ease of replacement without disconnecting the wiring, or to access to the internal programming switches, the unit can be withdrawn from the housing by pressing the release lever under the bezel and pulling firmly, holding the indents in the top and bottom of the bezel.
