ALARM BLOCK 1 TO 4: This function blocks the alarm at power-up when the unit
is first energized.
YES enables and NO inhibits this blocking function. When enabled the alarm will
not be active at power-up waiting for PV (Process Variable) to reach a non-alarm
situation. From this point on the alarm will be free to actuate should a new alarm
situation occur.
xya1
ALARM 1 HYSTERESIS: Defines the differential range between the PV value at
which the alarm is turned on and the value at which it is turned off (in engineering
units).
xya2
ALARM 2 HYSTERESIS: Same as above.
xya3
ALARM 3 HYSTERESIS: Same as above.
xya4
ALARM 4 HYSTERESIS: Same as above.
A1t1
ALARM 1 TIME 1: Defines the time (6500 sec. max.) during which the alarm 1
output will be ON when alarm 1 is active. Program zero to disable this function.
A1t2
ALARM 1 TIME 2: Defines the OFF state time for the alarm 1 output, after being
ON during the time selected on ALARM 1 TIME 1. Program zero to disable this
function.
A2t1
ALARM 2 TIME 1: Defines the time (6500 sec. max.) during which the alarm 1
output will be ON when alarm 1 is active. Program zero to disable this function
A2t2
ALARM 2 TIME 2: Defines the time during which the alarm 2 output will be, after
being ON during the time selected on ALARM 2 TIME 1. Program zero to disable
this function. Table 4 shows the advanced features that can be achieved with
these time functions.
