SECTION 12 • INSTALLATION

General

BE1-CDS240 Current Differential Systems are delivered with an instruction manual and BESTCOMS™ software in a sturdy carton to prevent shipping damage. Upon receipt of the relay, check the model and style number against the requisition and packaging list for agreement. If there is evidence of shipping damage, file a claim with the carrier, and notify the Basler Electric Regional Sales Office, your sales representative, or a sales representative at Basler Electric, Highland, Illinois.
If the BE1-CDS240 is not installed immediately, store it in the original shipping package in a moisture and dust free environment.

Contact-Sensing Input Jumpers

NOTE
The BE1-CDS240 relays with mid- or high-range power supplies are delivered with the jumpers in the H (HIGH) position. Read the following paragraphs before placing the relay in service.
BE1-CDS240 relays have eight or twelve contact-sensing inputs, depending on style number, to initiate relay actions. An external wetting voltage is required for the contact-sensing inputs. The nominal voltage level of the external dc source must comply with the dc power supply input voltage ranges listed in Section 1, General Information, Specifications. To enhance user flexibility, the BE1-CDS240 uses wide range ac/dc power supplies that cover several common control voltages. The contact sensing input circuits are designed to respond to voltages at the lower end of the control voltage range while not overheating at the high end of the range.
Energizing levels for the contact-sensing inputs are jumper selectable for a minimum of approximately 5 Vdc for 24 Vdc nominal sensing voltage, 26 Vdc for 48 Vdc nominal sensing voltages, or 69 Vdc for 125 Vdc nominal sensing voltages. See Table 12-1 for the contact-sensing turn-on voltages.

xxxx2xxxxxx 125/250 Vac/dc
xxxx3xxxxxx 24 Vdc n/a n/a Approx. 5 Vdc
* AC voltage ranges are calculated using the default recognition time (4 ms) and debounce time (16 ms).
Each BE1-CDS240 with a mid- or high-range power supply is delivered with the contact-sensing jumpers installed (H position) for operation in the higher end of the control voltage range. If the contact-sensing inputs are to be operated at the lower end of the control voltage range, the jumpers must be changed to L position.
The following paragraphs describe how to locate and remove/change the contact sensing input jumpers.
1. Remove the drawout assembly by pulling the two latches outward and sliding the assembly out of the case. Observe all electrostatic discharge (ESD) precautions when handling the drawout assembly.

2. Locate the eight jumper terminal blocks (or 12, Option A) that are mounted on the Input/Output Circuit Board. The Input/Output Circuit Board is the middle board in the assembly and the jumper terminal blocks are located on the back edge on the component side of the circuit board. Each terminal block has three pins. With the jumper as installed at the factory, one pin should be visible when viewed from the rear of the unit. Figure 12-1 illustrates the location of the jumpers placed in the high voltage position.
3. To select operation at the lower end of the control voltage range, position the blue jumper on the two terminals closest to the rear of the circuit board (L). Use care when removing each jumper so that no components are damaged.
4. When all jumpers are positioned for operation in the desired control voltage range, prepare to place the drawout assembly back into the case.
5. Align the drawout assembly with the case guides and slide the assembly into the case.
6. Push the latches down until they are parallel with the front panel.

Trip Coil Monitor (TCM) Jumpers

BE1-CDS240 relays have four trip coil monitor circuits for monitoring up to four breaker trip coils. Each TCM includes a High/Low Input jumper and a TCM On/Off jumper. The High/Low jumper establishes the operate voltage level of the Input as explained above and the On/Off jumper enables or disables the TCM logic. The TCMs are associated with Outputs 7, 8, 9, and 10. Relays are shipped with the jumpers in the TCM ON (active) position. To move the jumper to the off position, follow the procedure outlined under
Contact Sensing Input Jumpers and look for the terminals labeled TCM as shown on Figure 12-1.
Figure 12-1. Contact-Sensing and TCM Jumper Locations

Mounting

Because the unit is of solid-state design, it does not have to be mounted vertically. Any convenient mounting angle may be chosen. BE1-CDS240 Overcurrent Protection Systems are available in Basler Electric's MX case design. MX cases are fully drawout with current circuit shorting provisions. MX cases are available in four configurations: a standard 19-inch rack horizontal mount, a horizontal panel mount, and two vertical panel mounts (I/O Option "A" and I/O Option "E"). The short vertical panel mount configuration fits cutout and panel drilling dimensions of Basler Electric M1, GE M1 and M2, and Westinghouse FT31 and FT32 size cases. The long vertical mounting pane fits cutout and drilling dimensions of the GE L2 and Westinghouse FT42 cases.
