Circuit Board 12 34 5 6 7 8 B A U 64 32 16 8 4 2 1 D- D+ ~ ~ 2 LTR-RSS User’s Guide 3 On the face of the cover plate, you will see a 10-position knob (to select which schedule you want active), a button to send your changes to the Master, and status lights which confirm that your changes occurred. LTR-RSS User’s Guide Specifications Power Input: 9-24V AC/DC, 1W max. For cable between the LTR-RSS and LTR8-512 less than 100 ft, power can be drawn from the 12V output on the LTR8-512’s I/O connector. For longer cable, power should be drawn from a bell transformer or Lathem 24V power supply (typically a PS8-24). Low voltage wire is recommended 4 LTR-RSS User’s Guide Communications: EIA / IEEE RS-485 half-duplex requiring single twisted-pair (UTP or STP) communications cable (typically CAT-3 or CAT-5). Max length 4000 ft. Can be included on LTR8-512’s RS-485 Host Communications Bus, along with other Lathem RS-485 devices Terminal Block: 4-screw removable terminal plug supports both power (2-wire) andcommunications (2-wire) connections. Requires 3/32" flat- head screwdriver 5 LTR-RSS User’s Guide Mechanical: Circuit board is mounted to an industry- standard double-gang switch plate. Plate is screwed into standard double-gang flush-mount electrical box (typically Wire-Mold Part # V5747-2, not included). Connection of cables between electrical box and LTR8-512 or power source should be through conduit or other means approved by electrical / fire codes for low-voltage wire Environmental: Operation 0°-85°C (32°-185°F); 2060% R.H., non-condensing 6 LTR-RSS User’s Guide Installing the LTR-RSS To install the Remote Schedule Selector/Bell Ringer, • Remove the LTR-RSS from its package and locate the dip switches (bottom center) on the back of the circuit board. • Set the dip switches to ON match the Master’s 2400 address (default = 65) 9600 1 2 345678 and baud rate. (Press “*” at the Master to see its current address and baud rate). The legend on the circuit board will help you know which way to slide the dip switches. Use switch 1 to set the Baud Rate. Slide it down to choose 9600 baud (default) and up to select 2400 baud. BAUD6432168421 7 LTR-RSS User’s Guide To select the address, use the numbers that add up to equal the number of your Master’s address, then slide those switches down. For example, the default address is 065: switch 2 (value of 64) and switch 8 (value of 1) are down (64+1 = 65). For address 003, slide down switches 7 and 8 (2+1=3). For address 102, slide down switches 2, 3, 6 and 7 (64+32+4+2=102). • Locate the terminal block on the back of the circuit board (upper left). Attach the communication cable wire-pair (with proper polarity) to the top two screws on the terminal block. The top screw is Data - and the next one down is Data + . DD+ ~ ~ 8 LTR-RSS User’s Guide • Connect low-voltage power to the lower 2 screws on the terminal block. The LTR-RSS requires a voltage source of 9 to 24 volts, AC or DC. If the distance between the LTR8-512 Master and the LTR-RSS is less than 100ft, you can use a 2nd twisted-pair in the cable to bring power from the Master Terminals # 12 and 13 (on the rear of the Master's Display Panel, providing 12vAC at 250mA). You should use a separate low-voltage power supply or transformer if the cable would be longer than 100 feet or placed in areas of electrical interference that can cause problems for the Master. You should also place an in-line 250ma fuse on this connection. • Secure the cover-plate to the electrical box with four 6-32 FH screws. 9 LTR-RSS User’s Guide Wiring Diagram 10 LTR-RSS User’s Guide 11 Install Diagram Cable Plug Power Cable 9-24 VAC RS-485 Cable LTR-RSS User’s Guide Using the LTR-RSS When you make a schedule change, this change remains in effect until you make another change or when a programmed schedule change occurs. You can make schedule changes at the LTR-RSS, the MasterLink software or the Master itself. To deactivate all schedules: • Turn the knob to the ALL OFF position. • Push the ENTER SELECTION button. All LED’s will flash briefly and all schedules are deactivated. 12 LTR-RSS User’s Guide To activate a schedule: • Turn the knob to choose which schedule you want to activate. • After turning the knob, push the ENTER SELECTION button. • The indicator (LED) will light to show which schedule is now active. The LED stays lit for five (5) seconds then turns off to conserve power. • All schedules other than the one you chose are now deactivated. 13 LTR-RSS User’s Guide To manually ring all bells: • Turn the knob to the RING BELLS position. • Push the ENTER SELECTION button. All bell circuits will become active and will remain active for as long as you press the ENTER SELECTION button. Note: The bell circuits could remain active up to 2 seconds after releasing the ENTER SELECTION button. 14 Limited One-Year Limited Warranty Lathem warrants the hardware products described in this guide against defects in material and workmanship for a period of one year f...
