Fault Current Preset Feature
This feature allows setting of the FAULT current without actually applying current to the load. The fault
current preset feature is applicable to the I1-LOW, I1-HIGH, I2-HARMONIC, I1&I2, I3, I3-WYE, I3-
PARALLEL, and I4-DC current modes.
To preset the FAULT current:
1. Select static operation mode.
2. Set prefault off.
3. Press and hold the [CURRENT] button.
4. After half a second, a beep will sound and the fault current setting (not measurement) will appear on
the [VALUE DISPLAY].
5. Increase or decrease as desired using the [MODIFY] knob. Then release the [CURRENT] button.
6. To apply the fault current, press [FAULT].
Note that, for the I1&I2 current mode, both the I1 and I2 level can be preset by toggling between the two,
using the [CURRENT] button. Similarly, for the I4-DC current mode, with the MTS-1720 on, both the I4
level and the AC current level can be preset by toggling between the two using the [CURRENT] button.
4.6.10 I3-PARALLEL Current Mode
The I3-PARALLEL current mode allows more than one current channel to be paralleled together, and be
controlled as if they were one current channel.
NOTE:
Paralleling only can be performed with MTS-1700 systems with an I3P current mode
selection on the front panel.
4.6.10.1
OUTPUT CAPABILITY.
For n current channels paralleled together:
Maximum power = n x 400 VA (for MTS-1710’s)
Maximum power = n x 1000 (for MTS-1710 + MTS-1720 systems)
3
Maximum current = n x 30 Arms
Maximum voltage = 44 Vrms
For one MTS-1710 + MTS-1720, three current channels are available.
