ACCUMULATED TOTAL
During a batch run, the Accumulated Total can be displayed by pressing
the ACCUM TOTAL key. In the non-operational state (i.e. when the batch
is complete), the ACCUM TOTAL key also functions as the PRESET key and
enables the Preset quantity to be changed.
The Accumulated Total cannot normally be reset, except by pressing the
internal Reset button (see section 9.4).
3.2 TEST MODE
The 214Di has a Test Mode which can be entered and exited by pressing
and holding the front panel keys in certain sequences to avoid accidental
entry or falsely starting a batch. To enter Test Mode, the front panel keys
should be pressed and held in the following order: the STOP key and then
the ACCUM TOTAL key.
Note the test mode cannot be entered while the instrument is in program
mode or preset mode.
The tests are as follows:
Relay 1 Test
By pressing the RUN key, the display will show
the test for Relay 1. The output will only
activate while the RUN key is being pressed.
Relay 2 Test
By pressing the STOP key, the display will show
the test for Relay 2. The output will only
activate while the STOP key is being pressed.
Display Test
By pressing the PROGRAM key, all segments of
the display will flash.
Note the relay outputs are only operated when external DC power is present.
And any batch in progress when test mode is entered is stopped and cannot be
resumed.
To exit Test Mode, the front panel keys should be pressed and held in
the following order: the ACCUM TOTAL key and then the STOP key.
