NOTE
• The cable length is up to 40 meters max unterminated total length within the same
building’s earth ground plane.
• When you change the HOA switch to Off, Auto, and Hand mode in the physical device,
there is a delay of one second. This is to avoid the switch mode to change when it is
mistakenly changed. So, if you want to see the switch mode to change, you need to keep
the switch in the required mode at least for one second, otherwise the device ignores the
change made by switch.
Hand Off Auto (HOA) Switch
HOA switches (physical) are provided for each output—Analog and Binary. HOA switches present on the both
CIPer Model 30 controller and EXPIO devices. You can configure the HOA modes via physical switches present
on the controller and Expansion I/O devices. The H-O-A switch overrides all the software commands when set
to HAND or OFF.
Digital Outputs (DOs)
• If you configure the HOA switches to Off Mode, the Physical Digital Output is disabled irrespective of
the Control program logic output.
• If you configure the HOA switches to Auto Mode, the Physical Output responses as per the value pro-
vided by the Control program logic output.
• If you configure the HOA switches to Hand Mode, the Physical Output is enabled irrespective of the
Control program logic output.
Analog Outputs (AOs)
• When the H-O-A switch is in HAND position, the H-O-A trimpot drives the output from 0–100% (0–20
mA or 0–10 VDC as appropriate) and it ignores the Control program logic output.
• When the switch is in OFF position, the output is at 0%. The trimpot value covers the full range of the
output regardless of the Control program logic output.
• If you configure the HOA switches to Auto Mode, the Physical Output responses as per the value pro-
vided by the Control program logic output.
