The trip level is set at „Ins.Tst.Level‟ page (Level 6, Screen 18) and is selectable.
If the „Insulation Test‟ is not selected by setting the „ITM Module‟ value to “None” then the MCR Relay
closes by operation of the start button.
6.2.2 Manual Insulation Test
A manual “Insulation Test” is provided as a maintenance/fault finding tool. The manual test can only be
carried out when the load is not energised. A manual insulation test is also prevented when operating
in snore mode.
Before a manual Insulation Test can be performed the following conditions must apply:
1.
The Insulation Test page being displayed. This is located on the „Insulation Test‟ screen (Level 3,
Screen 2).
2. Pilot must be healthy (and any previous trips reset).
3. Insulation Test function must not be tripped.
4. Outlet must not be running.
5.
Outlet must not be in the process of „closing‟.
6.
Outlet must not be „Paused‟.
When the above conditions are met the <TEST> key must be pressed and held (for the duration of the
test). After 3 seconds the manual insulation test is initiated. The test voltage is applied to the outgoing
feeder while ever the above conditions are held (including holding the <TEST> key). The test results
are continuously calculated and displayed. The operator should maintain the test at least long enough
for the readings to stabilise, this being a function of the cable length. Once the test is completed
(usually by releasing the <TEST> key) the results are held in memory until another insulation test is
commenced either manually or as part of the starting sequence, or IPM control power is lost.
If th
e „ITM Module‟ has been set to “None” then the manual test will not function.
The status of the manual insulation test is shown on the Insulation Test Screen (Level 3, Screen 2).
The three functions shown on the screen are
„Not Active‟, „Arming Man.Ins.Test‟ and „Manual Insulat.
Test‟.
The display will show the last measured value.
