6.2.4 Run Time Meter Programming
You may program any of the ordinary contact (digital or discrete) input chan-
nels to accumulate and report the number of hours that their respective input
circuits have been closed. Any such channels will never cause an alarm, but on
inquiry will recite the channel’s Closed Circuit message or the Open Circuit
message according to the status of the input, and will then report the accumu-
lated Closed Circuit time (run time) to the tenth of an hour.
u
To program channel ZZ for Run Time Meter operation, press:
5 ZZ 4 ENTER
u
To preset a starting value, press:
5 ZZ 4 V ENTER
where V may be any value from 0 to 99,999.9.
u
To delete the Run Time Meter programming, you must reprogram the
channel for any other type of alarm criteria.
As with channels programmed for NO ALARM (Status Only) operation, the
default Open Circuit message is “Channel N is off.” To record your own Open
Circuit message for channel ZZ, use program code 1 ZZ. The default Closed
Circuit message is “Channel N is on.” To record your own Closed Circuit
message for channel ZZ, use program code 2 ZZ.
6.2.5 Pulse Totalizer Function Programming
The Totalizer function counts the accumulated number of pulses (momentary
contact closures) occurring at the contact input for a channel which you have
programmed for Totalizer operation. This function is typically used to
accumulate the pulse output of rotary flow meters.
An alarm set-point may be programmed to create an alarm call upon reaching a
particular total value. Scale and offset factors are programmable, and user-
recorded messages may be used.
Any contact input channel may be programmed for the Totalizer function, up to
a total of 8 Totalizers. The input pulse rate must not exceed 100 pulses per
second, and if the rate is over 50 pulses per second, the pulses must have a 50%
duty cycle.
u
To program channel ZZ for Totalizer operation, press:
5 ZZ 7 ENTER.
Note:
This function must be done to Activate the Totalizer. It is only possible to
program up to 8 contact input channels for Pulse Totalizer. However, any 8
inputs may be used from the full set of contact inputs in your unit.
