dedicated system diagnostic-only alarm relay that
automatically energizes when the “WARNING
CHECK STATUS” message flashes on the
MEASURE screen. This occurs when the analyzer
detects a “fail” diagnostic condition. See PART
THREE, Section 6.1 for more details.
Except for STATUS relays, during calibration the relay
on/off states are affected in the same way as the analog
outputs by the “(HOLD/XFER/ACTIVE) OUTPUTS” screen
selection. These relays are also held at their present on/off
states, transferred to desired preset on/off states, or remain
active to respond to measured values.
Refer to PART THREE, Section 4.6 for relay setup details.
The modular construction of the analyzer simplifies field
servicing and provides electrical safety. The front door/
keypad assembly uses voltages no greater than 24 VDC,
and is completely safe to handle.
Opening the analyzer door accesses terminals inside the
enclosure for electrical connections. Line power must be
connected to specifically designated terminals on TB3.
WARNING:
REMOVE LINE POWER BEFORE NEARING THIS AREA
TO AVOID ELECTRICAL SHOCK.
All user-entered configuration values are retained indefi-
nitely, even if power is lost or turned off. The non-volatile
analyzer memory does not require battery backup.
A label with the analyzer model number, serial number,
build date, and other items is affixed to the top of the enclo-
sure.
