Alarm Standby Function
The 7HI/7HK have an Alarm Standby function to allow masking
of the process low alarm condition if the process variable has
not traversed the low alarm threshold for the first time.
7HI
Wiring
Do not run input wires with power cabling. Ground shields at one
point only. Use compensating cable for thermocouple wiring.
Relays are internally protected by a varistor. When inductive
loads (such as mercury contactors) are used, or external switches
are connected in series with internal contacts, high voltage
transients may affect performance of the instrument. In this case
it is recommended to install an additional RC snubber network
across the contacts as shown. Contact Barber-Colman.

Measurement Offset
A programmable sensor offset is provided for instances when it is
not possible to locate the sensor in the ideal location. This offset
can be applied to all inputs and is programmable for C or F.
