MODEL 1582-22L RF Protection Switch 1.0 General 1.1 Equipment Description The 1582-22L RF Protection Switch provides Auto, Manual or Remote latched relay switching between CH1 and CH2 RF signals from .95 to 2.15 GHz including 10 MHz and DC power for attached LNB or SSPB devices. Alarm conditions on CH1 and CH2 are either a contact closure to ground or an open (selectable). The logic controls two separate RF switches, A and B. Switching logic can be selected as follows: 1.

2.0 Installation 2.1 Mechanical The 1582-22L consists of one RF/Controller PCB and one smaller PCB containing the RF inputs and outputs. It is housed in a 1 RU (1 3/4 inch high) by 12 inch deep chassis. Redundant switching power supplies provide power for the assembly. The 1582-22L can be secured to a rack using the 4 holes on the front panel.
2.2 Input and Output Signals - Figure 2.2 shows the input and output connectors on the rear panel. J7 - MONITORS and CONTROLS Terminal Strip. See Table 2.1. A, B - RF & IF IN/OUT RF & IF Primary In/Out for switches A&B. See Table 2.2. AC2 AC1 B2 B B1 A2 A A1 J1 J2 J3 J4 J5 J6 GND 1 J7 14 A2, B2 - RF & IF IN/OUT RF & IF Back-up In/Out for switches A&B. See Table 2.2. AC1, AC2 - POWER IN AC inputs for switching power supplies. 100-240 ±10% VAC, 47-60 Hz.
2.3 Controls and Indicators - The following are the front panel controls and indicators. S3 - MANUAL SELECT 3-position switch manually selects CH1 or CH2 or puts the unit in AUTO mode (switch position determined by Alarm and Remote closures). S1 - SWITCH RESET S2 - HISTORY RESET Push-button resets switch to CH1 if it is good and Push-button resets ALARM switch is in LATCH mode. Also resets REMOTE HISTORY LEDs only. selection to normal AUTO operation.
2.3.1 PC Board Settings NOTE: Dot position means jumper goes from pins 1-2; non-dot means jumper goes from pins 2-3 JP1 - 3-pin jumper - 3-pin jumper that works with JP3 In the dotted position when CH1 alarms the 1582-22L will switch to CH2 until CH2 alarms. At this point, if CH1 is still in alarm, the switch will stay on CH2. When the CH1 alarm clears if CH2 is still in alarm, the switch will switch to CH1.
2.4 Operation 1. 2. 3. 4. 5. 6. 7. 8. Set the on board controls as desired (see Sections 2.3.1 and 2.5, and Figure 2.1). Install the 1582-22L in the equipment rack. Connect signals to the BNC connectors (J1-J6 and J8-J13). Connect to signals on the MONITORS AND CONTROLS connector, J7, as desired (see Figure 2.2, Table 2.1). Connect power via two power cords to AC1 and AC2. Manually switch between channels 1 and 2 and be sure switching occurs. Switch to AUTO.
2.5 Switch Mode Setup The following gives the switch mode settings of the on board controls that can be changed in the field with JP1, JP2, JP3, JP4; S4. ( Figure 2.3). All shown with external alarm = ground. 1) CH1 Prime Mode - Switches from CH1 to the CH2 only if CH1 alarms and CH2 is good. Switches back to CH1 when it is no longer in alarm or when both CH1 and CH2 are in alarm Non-dot JP1, JP3, JP4; Dot - JP2; S4 - ALL TO OFF. 2) Latch to CH2 Mode - Switches from CH1 to CH2 if CH1 alarms and CH2 is good.
3.0 Environmental Use Information A. Rack-Mounting - To mount this equipment in a rack, please refer to the installation instructions located in the user manual furnished by the manufacturer of your equipment rack. B. Mechanical Loading - Mounting of equipment in a rack should be such that a hazardous condition does not exist due to uneven weight distribution. C.
