PTE-100-C PRO

So these are the basic steps for a
time
test:
1.
Switch the PTE-100-C PRO’s power output
and turn the
va-
riac
all the way to the left to reach the “0” position.
2.
Connect the relay’s measurement input (to where the CT or VT out-
put is normally connected) to the appropriate current or voltage
output tap.
3.
If you are doing a
current
based test, choose the current tap that
better accommodates the regulation range, turn its ‘flag’ LED on
using the
key and give a short press to
to ensure
that current, rather than voltage output, is displayed in Display #2.
If you are using a voltage output instead, press and hold
or
accordingly until a beep is heard to lock it to Display
#2.
4.
Connect the relay’s trip contact to the PTE-100-C PRO’s dry
(black/green) monitor input. This is for
dry
contact monitoring. If
you are detecting relay operation by means of a contact that is un-
der voltage, use the black and red connectors instead.
5.
Switch the power output
and gently turn the variac clock-
wise until the desired test value is displayed.
6.
Switch power
,
the timer and power
again
to start the test. If the adjusted test value is in the operating range of
the relay, it will eventually trip at the monitor input, the timer will
stop and the power output to the relay will be suspended (note that
the red output LED is now blinking).
7.
You will then be able to write down the values held by Display #1
(time) and Display #2 (operating voltage or current). Repeat steps
5 thru 6 for as many different current or voltage test values you
need to time.
