Chromalox 1604-7 P7 = analog retransmission initial scale value, P10 = Alarm 1 operating mode

Page 15

P7 = analog retransmission - initial scale value.

Available only when P5 = Pv.rt or SP.rt. It is programmable from -1999 to 4000.

The decimal point will be positioned as selected with P2 parameter.

P8 = analog retransmission - full scale value.

Available only when P5 = Pv.rt or SP.rt. It is programmable from -1999 to 4000.

The decimal point will be positioned as selected with P2 parameter.

P9 = Output 2 function. nonE = output not used.

rEv

= Out 2 is used as control output with

 

reverse action.

dir

= Out 2 is used as control output with direct

action.

AL1.P =it is used as Alarm 1 output and the alarm 1 is programmed as process alarm.

AL1.b = it is used as Alarm 1 output and the alarm 1 is programmed as band alarm.

AL1.d = it is used as Alarm 1 output and the alarm1 is programmed as deviation alarm.

NOTE: If P9 has been changed to "rEv", the cycle time (Cy2) will be forced to 15 seconds.

If P9 has been changed to "dir", the cycle time (Cy2) will be forced to:

10 s when P22 is equal to "AIr"

4 s when P22 is equal to "OIL"

2 s when P22 is equal to "H2O".

P10 = Alarm 1 operating mode

Available only when P9 is equal to "AL1.P", "AL1.b" or "AL1.d".

H.A. = High alarm (outside for band alarm) with automatic reset (latched).

L.A. = Low alarm (inside for band alarm) with automatic reset (latched).

H.L. = High alarm (outside band) with manual re- set (latched).

L.L.= Low alarm (inside band) with manual reset (latched).

P11 = Output 3 function nonE = output not used.

rEv

= Out 3 is used as control output with

 

reverse action.

dir

= Out 3 is used as control output with direct

 

action.

AL2.P =it is used as Alarm 2 output and the alarm 2 is programmed as process alarm.

AL2.b = it is used as Alarm 2 output and the alarm 2 is programmed as band alarm.

AL2.d = it is used as Alarm 2 output and the alarm 2 is programmed as deviation alarm.

NOTES: 1) If P11 has been changed to "rEv", the cycle time (Cy3) will be forced to 15 seconds.

If P11 has been changed to "dir", the cycle time (Cy3) will be forced to:

10 s when P22 is equal to "AIr"

4 s when P22 is equal to "OIL"

2 s when P22 is equal to "H2O".

2)The relations among P5, P9 and P11 are shown by the following notes:

-one Out only can be configured as "rEv" output.

-one Out only can be configured as "dir" output.

-if no Output is configured as control output the instrument will operate as an indicator.
