Trip Type

12 - H TEMP

H TEMP (Hysteresis Temperature) controls the Alarm based on the internal temperature of the MDI. T1READ

sets the low temperature (temperature at which the Alarm turns on) in °C. T1WIN sets the number of
degrees above the low temperature at which the Alarm turns o (also in °C).

Slave Sensor Power Congurations

The MDI Slave Sensor Power Transistor allows you to use the MDI batteries to power your slave sensor. The

Slave Sensor Power Transistor is controlled by three trip types: Type 6 - O, Type 8 - On, and Type 9 - Timed

Interval. Trip Types can only be changed when the MDI is not in a hazardous location (or the hazardous
atmosphere has been cleared).

In these scenarios, Interval Time governs the time between each power up of the slave sensor, On Time

determines how long the slave sensor is powered up, and Auto-O determines how long the display is

powered on.

Self-Contained IS System - Intermitant to Infrequent Monitoring

For self-contained IS systems that are not regularly monitored, set the MDI to turn itself on and power up

the slave sensor only when the external Decrease/Power Button is pushed. Setting the Auto-O to 300
seconds means the reading will be displayed for ve minutes before the MDI turns itself and the slave
sensor o.

• Trip 1 Type: 9 - Timed Interval

• Interval Time: 0

• On Time: 120 seconds

• Auto-O: 300 seconds

Or

• Trip 1 Type: 8 - ON

• Auto-O: 300 seconds

Self-Contained IS System - Frequent Monitoring

For self-contained IS systems that are monitored regularly, set the MDI to turn itself on and power up the
slave sensor often enough that readings are likely to be displayed when monitoring occurs.

• Trip 1 Type: 9 - Timed Interval

• Interval Time: 45 minutes

• On Time: 120 seconds

• Auto-O: 300 seconds

IS System with Passive Control Equipment

For IS Systems with Passive Control Equipment, the Passive Control Equipment will be sning the slave

sensor reading from the MDI, so set the MDI to turn itself on and power up the slave sensor as often as you

want the control system to be updated. Auto-O time is less critical, as physical observation redundant to
the Passive Control Equipment sning of the MDI.

• Trip 1 Type: 9 - Timed Interval

• Interval Time: 15 minutes

• On Time: 30 seconds

• Auto-O: 90 seconds

 IMPORTANT: When Interval Time is set to 0 minutes, the MDI can only wakened by

pushing the external decrease/power button.

 NOTE: Higher settings for On Time and Auto-O will drain the battery faster. Use lower

settings to turn the sensor and display o sooner, which will extend battery life.

 NOTE: Battery meter will display incorrectly while MDI is powering slave sensor. Meter

will be accurate again after slave sensor is powered down.
