| Series Features |
| CAP Series AC/DC Overcurrent |
| Series Description: The CAP Series current sensing relay is used to detect an AC or DC overcurrent condition. It has two operating modes: non-latching or latching. Each relay has three top-mounted potentiometers: one for selecting the pick-up setting within the selected monitored current range (Threshold), one for selecting the drop-out setting of 5-50% below pick-up setting (Hysteresis), and one for setting the start- up sensing delay (ts). This delay, which is adjustable from 0.1 10 seconds, inhibits energization of the output relay during the start-up period. CAP Series relays have three built-in current ranges (see right) to monitor both AC & DC current. Each one is easily selectable by connecting to the corresponding terminal and to the COM terminal (see Wiring Diagram below) Non-Latching Mode: The unit will operate in the non-latching mode if no circuit is completed across pins 9 & 11. After input voltage is applied (LED is Green) and the start-up sensing delay (ts) of 0.1 10 seconds is completed, the relay will energize when the monitored current is above the adjustable pick-up setting (Threshold). The LED will be Red. It will de-energize when the monitored current goes below the adjustable drop-out setting (Hysteresis) by 5-50% of the selected pick-up setting or when input voltage is removed. The LED will be Green. Latching Mode: The unit will operate in the latching mode if a N.C. contact (Memory S2) is connected across pins 9 & 11 (see Wiring Diagram). After input voltage is applied (LED is Green) and the start-up sensing delay (ts) of 0.1 10 seconds is completed, the relay will energize when the monitored current is above the adjustable pick-up setting (Threshold). The LED will be Red. It will de-energize when the monitored current goes below the adjustable drop-out setting (Hysteresis) by 5-50% of the selected pick-up setting and the N.C. contact (Memory S2) is opened, or when input voltage is removed. The LED will be Green. It is recommended to set the Hysteresis at 5% when in the latching mode. |
