2.6.2 Remote Switch(es)
The unit is provisioned to connect remote switches (DS/REMS1/REMS2) directly to the control system through the
REM connector located in the evaporator section.
• Two types of switches may be used:
1. A switch with contacts that are open when the switch is activated.
2. A switch with contacts that are closed when the switch is activated.
• Four Configurations are available for each switch.
1. Activate an alarm only while the switch is activated.
2. Activate an alarm and shut the unit down while the switch is activated. The unit will remain shut down for a min-
imum of three minutes under this setting.
3. Activate the alarm and bring the engine into low speed while the switch is activated.
4. Record the switch activation in the data recorder.
• If configured to shut the unit down or bring the engine to low speed an additional choice will be available. The
additional choice allows the unit to be set so that the configured action will always take place OR the configured
action will only take place when the ambient temperature is below a certain temperature. for example, if the
shutdown/low speed temperature choice is set to 77°F (25°C) the unit will only shutdown/ go to low speed if the
ambient temperature is below 77°F (25°C).
• Additionally a Functional Parameter “override” setting will be available for each switch configured to shut the
unit down. The Functional Parameter may be set to “YES” or “NO”. If the Parameter is set to “NO” the config-
ured action will not be overridden. If the Parameter is set to “YES”, the alarm will be activated but the unit will
not shutdown.
