The HPL110A functions in these examples are as follows:
P -
Power %kW:
The display shows true power in units of % of full scale for the
HPL110A as installed.
Ts - Start Delay Timer:
Ts is used to delay the start of active monitoring until after
the start surge is completed.
The HPL110A assumes that the motor is OFF when measured load - %kW - is
below 5% full scale. The Ts timer starts when the load reaches 5% and
monitoring is disabled for the duration of the Ts period. Ts is programmable
in the range 0.1 to 99.9 seconds.
On conclusion of the Ts period, monitoring becomes active.
If P drops below 5%, monitoring is immediately disabled and a new Ts period
will start as soon as load again reaches 5%.
L1 - Max. Limit:
Max. alarm limit programmable in the range 5% to 100% / OFF
and used in conjunction with the Tr1 Reaction Timer. A Max. Limit alarm is tripped
if P exceeds L1 for a period Tr1.
Tr1 - Reaction Timer:
Used in conjunction with the L1 Max. Limit and programmable
in the range 0.0 to 99.9 seconds. Tr1 is time for which the P must remain above
the L1 Max. Limit before an alarm is declared. If P falls below the L1 during the
Tr1 timer period, the timer is re-set to zero.
Note:
if Tr1 is set to 0.0 seconds, actual reaction time will be one cycle or approx.
16 msec. at 60Hz and 20 msec. at 50Hz
L2 - Min. Limit:
Min. alarm limit programmable in the range OFF / 5% to 100% and
used in conjunction with the Tr2 Reaction Timer. A Min. Limit alarm is tripped
when P remains below the L2 Min. Limit for a period of time Tr2.
Tr2 - Reaction Timer:
Used in conjunction with the L2 Min. Limit and programmable
in the range 0.0 to 99.9 seconds. Tr2 is time for which the P must remain below
the L2 Min. Limit before an alarm is declared.
D
- Max.
Level:
If the
D
up arrow key is depressed while the HPL110A is in monitor
mode, the display will show the maximum load - in %kW - experienced since
the last Ts.
Ñ
- Min. Level:
If the
Ñ
down arrow key is depressed while the HPL110A is in monitor
mode, the display will show the minimum load - in %kW - experienced since the
last Ts.
