20 SI400 APPENDIX
This sections describes the differences between the SI100/SI200 as described in this document and the operation of the SI400 unit.
20.1 SI400 SUMMARY
The SI400 is a device that can accommodate up to four channels, and as such does not provide the measurement computation facilities
(A+B, A+B/2, A-B etc) that the SI100/SI200 provide, as the number of possible computations for a four channel device is prohibitive. It
does however allow for each channel to monitor “Max-Min” as well as tracking channel input value and also provides Preset, ABS and
ZERO controls for each channel, configured individually or all channels together.
The basic operation of the SI400, the menu system, its discrete inputs and outputs, adding digital probes etc, do however align with the
ACS methodology, the menu's should be navigated the same and the parameters adjusted in the same manner.
20.2 SECTION 9.1 - SI100 AND SI200 DISPLAYS
As per all SI Series products, the SI400 has three main screens (excluding menu), which provide information as described below.
The charts shown on any of these screens include small triangles along the bottom edge which indicate the alarm setpoints for a given
channel.
20.2.1 Screen 1 & 2
The first screen of the SI400 unit shows channels 'A' and 'B', with channel 'A' at the top and channel 'B' at the bottom. Each channel
display provides a chart covering the full range of the probe as well as a reading, channel status (Range Error etc), measurement 'Mode'
type ('Value' if tracking input or 'Max-Min') and a Pre/Zero/Abs indicator for each channel.
Screen two is the same as screen one except channels 'C' and 'D' are shown.
The format of screens 1 & 2 are shown below (note: Screen one, showing channels 'A' and 'B' is shown here): -
