10 T ime synchronization between multiple PTC901 meters can be accomplished through a hardware interface on the Real-T ime Clock option card. This RS485 type interface allows connection of up to 32 PTC901 meters in a two-wire multidrop network, at distances up to 4000 ft.
11 PROGRAMMING MODE ENTR Y (P AR KEY) The Programming Mode is entered by pressing the PA R key . If this mode is not accessible, then meter programming is locked by either a security code or a hardware lock. (See Modules 2 and 3 for programming lock-out details.
12 This parameter determines how the T imer Input Signals affect the “Run/Stop” status of the T imer . The timing diagrams below reflect a Sinking input setup (active low). A Sourcing input setup (active high) is available through plug jumper selection (see Section 2.
