Page 3: General Description
GENERAL DESCRIPTION The PTC900 (Timer) and PTC901 (Clock/Timer) offer many features and performance capabilities to suit a wide range of industrial applications. Both can function as an Elapsed Timer or Preset Timer, while the PTC901 also offers Real-Time Clock with Date capability. The Plug-in option cards allow the opportunity to configure the meter for the present application, while providing easy upgrades for future needs. - Page 4 DISPLAY: 6 digit, 0.56" (14.2 mm) red sunlight readable or standard green 2. POWER: AC Versions (PTC901, PTC900): AC Power: 85 to 250 VAC, 50/60 Hz, 18 VA Isolation: 2300 Vrms for 1 min. to all inputs and outputs. (300 V working)
- Page 5 Plug-in cards. Adding Option Cards The PTC900/PTC/901 series meters can be fitted with up to three optional plug-in cards. The details for each plug-in card can be reviewed in the specification section below. Only one card from each function type can be installed at one time.
- Page 6 1.0 I NSTALLING THE Installation The meter meets NEMA 4X/IP65 requirements for indoor use when properly installed. The meter is intended to be mounted into an enclosed panel. Prepare the panel cutout to the dimensions shown. Remove the panel latch from the meter.
- Page 7 3.0 I NSTALLING The Plug-in cards are separately purchased optional cards that perform specific functions. These cards plug into the main circuit board of the meter. The Plug-in cards have many unique functions when used with the meters. CAUTION: The Plug-in card and main circuit board contain static sensitive components.

Timer (TMR), Cycle Counter (CNT), or Date (DAT). The Time Display for the Real-Time Clock is shown with no annunciator. Any of these displays can be locked from view through programming. (See Module 3.) PROGRAMMING MODE Two programming modes are available. - Page 12 6.1 MODULE 1 - T Module 1 is the programming module for the Timer Input Parameters. In the Display Mode, the TMR annunciator indicates the Timer display is currently being shown. An EXCHANGE PARAMETER LISTS feature, which includes the Timer Start and Timer Stop Values, is explained in Module 2. TIMER RANGE 23 TIMER RANGE SELECTIONS = SEC;...
- Page 13 Two lists of parameter entries are available for the Timer/Counter Start and Stop Values; Setpoint On/Off and Time-Out Values; and Setpoint Daily On/Off Occurrence (for Real-Time Clock option). The two lists are named . If a User Input is used to select the list, then the User Input is in the inactive state and in the sublist.
- Page 14 DISPLAY SELECT (Level Active) When active (maintained action), the meter continuously scrolls through all displays that are not “locked-out” in the Display mode. (See Module 3 for Display Lock-out details.) A sub-menu provides Scrolling Speed selection. DISPLAY SELECT (Edge Triggered) When activated (momentary action), the meter advances to the next display that is not “locked-out”...
- Page 15 CHANGE DISPLAY INTENSITY LEVEL When activated (momentary action), the display intensity changes to the next intensity level (of 4). The four levels correspond to Display Intensity Level ) settings of 0, 3, 8 & 15. The intensity level, when changed via the User Input/Function Key, is not retained at power-down, unless Quick Programming or Full Programming mode is entered and exited.
- Page 16 The annunciators to the left of the display indicate which display is currently shown. Timer (TMR), Cycle Counter (CNT), or Date (DAT). The Time Display for the Real-Time Clock is shown with no annunciator. Any of these displays can be locked from view with the DISPLAY LOCK-OUT parameters.
- Page 17 6.4 MODULE 4 - C Module 4 is the programming module for the Cycle Counter Parameters. In the Display Mode, the CNT annunciator indicates the Cycle Counter display is currently being shown. An EXCHANGE PARAMETER LISTS feature, which includes the Cycle Counter Start and Stop Values, is explained in Module 2. CYCLE COUNTER COUNT SOURCE This parameter selects the source from which a count is added to or subtracted from the Cycle Counter.

Discard the separate bulletin when using Setpoint plug-in cards with the PTC901 and PTC900. SETPOINT SELECT Select the Setpoint (alarm) output to be programmed. This provides access to the parameters for that particular Setpoint.
- Page 20 Time-Out Value is 99 minutes 59.99 seconds. PTC901: DAILY ON OCCURRENCE This parameter only appears when the Setpoint is assigned ( Real-Time Clock Time display ( ). This parameter determines the days of the week when the Setpoint output will activate.

This section of the PTC900/PTC901 bulletin replaces the bulletin shipped with the RS232 and RS485 serial communications plug-in cards. Discard the separate bulletin when using those serial plug-in cards with the PTC900/PTC901.
- Page 22 SENDING SERIAL COMMANDS AND DATA When sending commands to the meter, a string containing at least one command character must be constructed. A command string consists of a command character, a value identifier, numerical data (if writing data to the meter) followed by the command terminator character * or $.

The abbreviated response suppresses the address and register mnemonics, leaving only the numeric part of the response.
- Page 24 Character Frame Figure 6.8 MODULE 8 - R Module 8 is the programming module for the Real-Time Clock (RTC) Date and Time Parameters. In the Display Mode, the DAT annunciator indicates the RTC Date is currently being shown. The RTC Time display is shown with no annunciator.
- Page 25 In this configuration, one meter is designated as the Serial RTC Master by setting the meter's address as 98 or 99 (see Serial Real-time Clock Addressing in Master Module 7). Every hour (at 30 min past the hour), the Serial RTC Master / Host will transmit the full time (Hours, minutes, seconds) to all meters through the RS485 serial card wiring network.
