Data sheet Insulation monitor, SIM-Q/SIM-Q LF TCM-2 Thyristor Control Module TCM-2 Thyristor Control Module DATA SHEET DATA SHEET DATA SHEET Insulation monitor, ADL-111Q96  Monitoring of insulation resistance on a DC network  24 V, 110 V or 220 V DC  Accepts up to 120µF leakage capacitance

Data sheet Application The ADL is used for supervision of the insulation resistance between an insulated voltage distribution network (IT network) and earth cable/safety cable. The instrument is applicable in conjunction with DC networks of 24 V, 110 V or 220 V DC. This type of insulation measurement is only carried out on DC networks where both conductors are isolated from the protective earth/the hull of the ship. The ADL can be used for marine installations and other types of insulated voltage networks, for example DC manoeuvre voltages of transformer stations. Measuring principle The...

Data sheet Product variants The ADL is available in two different versions – standard and advanced. Standard versions: Type Network/aux. voltage Measuring range 1µF or 20µF maximum capacitance on network (user-selectable via S1 under the rear cover). See ADL Quick guide. Set point adjustment from ohm scale at the rear of the instrument. Set point The requested alarm limit value is set on an ohm scale at the rear of the instrument.

Data sheet Advanced versions: Type Network/aux. voltage Measuring range 1µF to 120µF maximum capacitance on network (selectable via S1 under the rear cover). See ADL Quick guide. Set point is automatically visible on front scale during power-up and adjustment. Due to the low injection voltage, problems with activation of possible over-voltage protections are eliminated. Set point A new feature makes accurate setting of set point much easier. When the set point potentiometer at the rear of the instrument is turned, the product automatically goes to meter indication of set point during...

Data sheet Connection diagram + DC Source Test resistance Instrument shown as self powered * recommended values The auxiliary supply should be protected by means of a 2 A fuse. Test If a periodical test function is required, it can be achieved as shown in the connection diagram above. Warning If the installation is to be tested by means of a high-voltage "MEGGER", the measuring wire to the ADL must be disconnected before testing is carried out.
