INSTRUCTION MANUAL 1582-70L SWITCH

1.1 Equipment Description - The 1582-70L Switch provides AUTO or Manual latched relay switching

between CH1 and CH2 RF signals.(DC - 1.5 GHz). Automatic control determines switch routing by monitoring
alarm inputs on two channels (CH1, CH2) and selecting the initial source. Local and remote control of RF sources
is also provided. Latching relays allow the switch to remain in its "current" state independent of power loss.
The 1582-70L detects an external alarm condition on CH1 and CH2 by either a contact closure to ground or an
open (selectable). Switching logic can be selected as follows:

1) CH1 Prime Mode - Switches from CH1 to 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

2) Latch to CH2 Mode - Switches to CH2 if CH1 alarms and CH2 is good. Latches to CH2. Push

Manual Reset or ground Remote Reset pin to return to CH1 if it has no alarm or both CH1 and CH2
are in alarm.

3) Minimum AUTO switching, Initial Channel Select (ICS) Mode - Switch stays on channel last

selected by Manual or Remote selection after return to AUTO. AUTO switching occurs only if current

channel alarms and the other channel is clear.
Switching is accomplished using latching relays so if power is removed from the 1582-70L, CH1 and CH2 RF will
continue to go to the output selected prior to power loss and will remain there when power is applied assuming no
change in alarm status from when power was lost. The channels can be manually switched by the front panel Manual
Select switch. If operating in the ICS mode, the last channel manually selected (CH1 or CH2) will be the initial
channel when returning the Manual Select switch to AUTO. External REMOTE contact closures can force selection
of CH1 or CH2 when the Manual Select switch is in the AUTO position independent of the alarm conditions of CH1
or CH2. Front panel LEDs indicate alarms, alarm history (prior occurrence of alarms which have now cleared),
switch conditions for CH1 and CH2, REMOTE or MANUAL operation and presence of power.
RF connectors are BNC, female. Contact closure inputs are via barrier strip. Dual power supplies provide redundant

power to the 1582-70L. The chassis is a 1 3/4” rack mount.
