Chromalox 1604 User Manual

13
energized during the ON status of the
instrument output (relay energized or SSR
output status 1).
n.C. = Set P10 to n.C. when the load is energized
during the OFF status of the instrument
output (relay de-energized or SSR output
status 0).
P11 = Current transformer range
This parameter is present only if P10 is different
from OFF or SP2 and it is programmable from 10
to 100 A.
P12 = Output 3 function
0 = Output not used for alarm 2.
1 = it is used as alarm 2 output and the alarm 2
is programmed as process alarm.
2 = it is used as alarm 2 output and the alarm 2
is programmed as band alarm.
3 = it is used as alarm 2 output and the alarm 2
is programmed as deviation alarm.
NOTE : The output 3 relay operates as a logic OR
between the alarm 2 and the "OUT 1 failure
detection" function.
P13 = Alarm 2 operating mode & OUT 1 failure
detection reset
Available only when P12 is different from 0 or P10
is equal to n.O or n.C.
H.A. = High alarm (outside for band alarm) with
automatic reset.
L.A. = Low alarm (inside for band alarm) with
automatic reset.
H.L. = High alarm (outside band) with manual
reset (latched).
L.L. = Low alarm (inside band) with manual reset
(latched).
NOTE:The "Out 1 failure detection" function
assumes only the selected reset type (manual or
automatic).
P14 = Programmability of the alarm 2
threshold and hysteresis values
Available only when P12 is different from 0.
OPrt = Alarm 2 threshold and hysteresis are
programmable in the operating mode.
COnF = Alarm 3 threshold and hysteresis are
programmable in configuration mode.
P15 = Alarm 2 threshold value
Available only when P12 is different from 0 and
P14 is equal to "COnF".
Range: For process alarm - within the range limits.
For band alarm - from 0 to 500 units.
For deviation alarm - from -500 to 500
units.
P16 = Alarm 2 hysteresis value
Available only when P12 is different from 0 and
P14 is equal to "COnF".
Range: from 0.1% to 10.0 % of the range
selected with P3 and P4 parameters or
1 LSD.
P17 = Threshold of the “Soft Start” function.
Threshold value in eng. units to initiate the "Soft
start" function (output power limiting) at start up.
Range : within the readout span.
NOTE: This threshold value will not be taken into
account when tOL = InF.
